Signature comparison
This card. The signature as cropped from the slab photo (front).
Below, the known examples Crown compared it with. Examples with stronger proof (signed in front of staff, or certified by an independent authenticator) carry the most weight.
Feature by feature
| Feature | This card | Known examples | Result |
|---|---|---|---|
| Overall form and proportions | Compact two-part signature: an abbreviated 'Mk' cluster, then a 'P' followed by a 't'/'o'-type terminal with a long horizontal crossbar. The second element is larger and dominant. | All usable references show the same abbreviated 'Mk P–t' structure with the surname element dominant (R1–R7). R4 and R6 are especially close in compressed proportions. | Match |
| Slant and baseline | The signature runs vertically up the right edge of the sticker. Read along that axis, it has a moderate forward slant and a gently rising baseline. | The references show a forward slant and a slightly rising baseline, most clearly in R3, R5 and R7. | Match |
| Letter construction | The M is a fast zigzag/'7l'-like form with a hooked entry, followed by a small looped k/h. The P is built from a downstroke with a looped bowl and a descending stem. The terminal 't' has a long crossbar. | Every reference uses the angular zigzag M, a small k/h, a P with a bowl and long descender, and a t/o terminal with an extended cross. Our M is more rounded and compressed than the Funko versions, but it resembles R4 and R6. | Natural variation |
| Connecting strokes | The M and k are connected in one movement, with a lift before the P. The P and terminal are partly connected. | The references show the same pattern: a connected M–k, a pen lift, then the P and t/o group (R3, R6, R7). | Match |
| Starting and ending strokes | The entry stroke on the M is hooked and appears tapered. The crossbar ends in an extended exit stroke that looks tapered rather than blunt. | The references show a hooked or angled M entry and a long, flicked crossbar exit (R5, R6, R7). | Match |
| Line quality and speed | Strokes look fluid and rapid, with no visible tremor or drawn quality at this resolution. White speckle voids appear inside the ink, consistent with marker ink beading on a glossy sticker surface. | The references show fast, confident strokes. R6 and R7 on paper show smooth, solid ink. | Match |
| Pen pressure pattern | Ink is darker where it crosses the green snake art and lighter, with skipping, on the blue background. Width varies along the strokes. | Paint-marker references show uniform heavy coverage. Fine-tip references (R6, R7) show some variation in stroke width. | Natural variation |
| Spacing | There is a clear gap between the 'Mk' cluster and the 'P–t' surname element. | The same gap between the first-name and surname groups appears in R1–R7. | Match |
| Flourishes and underlines | There is no underline. The extended crossbar serves as the only flourish. | No reference has an underline, and the extended crossbar is the habitual flourish in all of them. | Match |
| Placement and size | Signed vertically in the open blue background on the right side of the sticker, partly over the snake art. Moderate size. | The references are placed in open areas of each item. Size scales with the item and marker. No fixed facsimile location is evident. | Natural variation |
| Reproduction indicators | No halftone or dot pattern is visible within the strokes at this resolution. The ink appears to sit on the surface, with skipping voids typical of marker on gloss. | Not applicable. | Not assessable |
Examiner notes
Ours is on a 2022 Magic Marker Art Slop Culture Kids sticker, so it is most likely a 2022–2023 signature. R7 is dated 9/15 (2015). The Funko Pop references (R1–R3, R5) are probably 2021–2023 based on the products, and the Horrible Kids card references (R4, R8) are likely early-to-mid 2020s. R6 is undated. The core construction (zigzag M, small k/h, looped P with long descender, long-crossbar t) is stable from 2015 through the 2020s, so era is not a source of concern. The main differences come from surface and pen: fine-point and Sharpie on paper or card in R4, R6 and R7, versus a broad paint marker on box plastic in the Funkos and a blue marker on glossy sticker stock in ours.
How Crown authenticates autographs: the signature is compared with known examples gathered from Crown's own authenticated cards, independent authenticators and public listings, measured by software, examined by an AI forensic model, and signed off by Crown Grading staff. The decision above is Crown's.
