IMPERIAL TOYS KEYCHAINS
The Imperial Sell Sheet states a complete set consists of 24...however, many collector's also consider 18 to be a complete set. I have 18 in my collection and they are all in MINT condition, still in the original bag they were sold in at the store. Unfortunately they don't photograph well in the bag, since the bag has been beat up and is in fairly bad shape after years of wear and tear - but I decided to leave them sealed in the bag. Any 'scuff' marks, etc you see in the images below is on the bag and not on the plastic.
Each Keychain consisted of 2 characters from the Original 1st and Original 2nd Series Garbage Pail Kids - one on each side. They were packaged in a thin, plastic bag that were displayed in a large, clear plastic tub.
