It measures approximately 7" x 9 3/4". It is in excellent, unused condition and has never been removed from the paper backing.
I assume that that the adhesive on the sticker is still strong but can not guarantee it as this is a 35+ year old sticker. Please note that the sticker had been stored in a magnetic sticky photo album/sticker book so there is a bit of residue on the back of the paper backing as well as some loss of the printing, see photo 4. There appears to be no damage to the actual sticker. The album was stored in a cool, dry, smoke free basement since the 1980s. I will be listing additional vintage 1980s stickers including Lisa Frank ones.
