The ABCs of GPK Coloring Book

Released on January 22, 2019, The ABCs of GPK Coloring Book was the company's first online Garbage Pail Kids product of that calendar year. Offered directly through the Topps web store for $9.99, each order secured a twenty-six-page physical coloring volume bundled with an individual bonus sticker, with SmartPost shipping included at no extra charge for domestic buyers.

The booklet itself handed each slot in the alphabet over to a legacy subject, using line illustrations contributed entirely by veteran franchise artist Neil Camera. Each of the twenty-six interior pages matched a single letter to an established personality whose name shared that same initial, working through the alphabet with characters such as Kim Kong. The interior sheets provided line drawings of classic characters to color across the entire run.

The single loose sticker slipped inside each shipment, a rendition of Adam Bomb branded as "A is for Adam," proved popular with collectors. Topps produced this promotional piece across three distinct border variants, printing copies with green, pink, or gold edges. With an ultimate production total of one thousand books, the individual cards appeared in roughly balanced quantities, though the manufacturer never clarified if any particular border variation had been limited to a smaller press run than the others.
