10 Point Guide

Each number provides insigth to key detail of original cards.

1

Card Size

Cards measure approximately 2.95 inches in height and 2.16 inches in width, matching the original album placeholder dimensions.

2

Title Black Outline

All cards were done by industrial CMYK printing. All black outlines overlap the CMY. No solid black lines were printed. 

So even when something looks like a solid black area, under magnification you will see:

  • Black halftone dots

  • Overlapping CMY dots mixed with black

3

Halftone Print Pattern 

Cards display irregular CMYK halftone dots without repeating digital grid patterns, producing natural color blending rather than uniform rows or pixel-like structures.

4

Card Finish 

Cards have a subtle light ink gloss that appears soft and slightly matte under light, unlike reproductions which typically display a stronger mid-to-high glossy varnish coating that reflects light more sharply.

5

Card Stock 

Cards are printed on thin magazine-like paper with randomly distributed paper pulp fibers, while many reproductions use thicker cover-style stock that often shows more uniform or directional fiber patterns. Due to the card being printed on thin paper stock, this allows the front artwork to be faintly visible through the reverse side under natural light when placed on a white surface.

6

Reverse Orientation

Cards have the back printed in an inverted orientation, so when the card is flipped from left to right the reverse appears upside down, aligning correctly with the layout of the original album pages.

7

Reverse Card Brand

Cards display the character name upside down at the top of the reverse side, printed in dark brown to bold brass-tone solid ink, slightly imperfect  resembling a stamped impression rather than the halftone dot patterns used on the front artwork. Some examples with have text more sharp but the font remains the same style.

8

Reverse Card Number Mark 

Cards feature the card number printed upside down in the center of the reverse inside a circle, using dark brown to bold brass-tone solid ink with slightly imperfect edges resembling a stamped impression rather than halftone printing.

9

Reverse “GARBAGE GAN” Text 

Cards include the text “GARBAGE GAN” printed vertically on the right side of the reverse, an original misspelling, rendered in dark brown to bold brass-tone solid ink with slightly imperfect, stamp-like text rather than halftone printing. Some examples with have text more sharp but the font remains the same style.

10

Reverse Character Name 

Cards display the text “LA PANDILLA BASURA” upside down at the bottom of the reverse side, printed in bold brass-tone solid ink with slightly imperfect, stamp-like edges rather than the halftone dot patterns used on the front artwork. Some examples with have text more sharp but the font remains the same style.
