All-New Series 4

When Topps released All-New Series 4 in April 2005, the set marked the twentieth anniversary of the Garbage Pail Kids franchise. The collection balanced continuity with fresh blood, pairing original series stalwarts Tom Bunk, John Pound, and James Warhola with concept work from Jay Lynch, alongside newer illustrators such as Luis Diaz, Ray Lago, and David Gross. Bunk and Pound carried the heaviest painting load across the eighty base stickers, while the gag writing was split among Lynch, Pound, Bunk, art director Jeff Zapata, and John Williams. Among the characters in the roster were Paris Embarrassed, Maris Wiltin', Paul Vault, Impaled Dale, Spongey Spencer, and Grunge Bob.

The release was split across two distinct distribution avenues, stocking hobby outlets as well as retail shelves in ninety-nine cent foil wrappers. Full hobby and retail boxes each packed thirty-six foil packs, with every individual pack carrying five stickers, a single game card, and a rules insert featuring a bonus code that buyers could use online to construct their own custom kid. Topps also stocked an eleven-pack retail bonus box, while special value boxes and blister packages held four unique bonus cards cataloged from B6 to B9. Perfect collation across a thirty-six pack box yielded just over two complete base sticker runs and slightly more than a single set of regular game cards.

Across the entire release, the checklist encompassed one hundred and fifty cards, dividing eighty base stickers from seventy chase items and introducing elements new to the franchise. Efrain Cintron of Apt. 5A provided rendered artwork of original figures across thirty-six game cards, thirty-three of which were common, but three were scarce gold foils seeded at long odds of one in seventy-two packs. Hobby boxes offered an exclusive draw of their own by including one autographed sketch card per box, marking the first time sketch cards, created by artists such as Don Perlin and Justin Green, had ever been inserted into packs.

Several cards across the run featured specific artistic and numbering details. Six separate card pairings hid the GPK acronym directly inside their background paintings, while five pairs, specifically numbers 17, 21, 23, 24, and 26 across both their a and b variants, were printed with black and white card numbers. On the reverse side, Jay Lynch and Scott Shaw contributed twenty Puzzle Puke pieces of artwork.
