NOTE:
- Sketch cards were an extremely RARE insert for the Garbage Pail Kids Flashback release.
- The odds of getting a sketch card is 1:229 packs (or one in every 10 boxes)
- Due to the extreme rarity of these cards, I will simply be showcasing the cards I've been lucky enough to add to my collection.
- Keep checking back to see if I've been lucky enough to score another one!
