Mushroom stickers from Marks, purchased about 10 years ago. Unused and stored in a file. I don't see these very often, so I think they're rare. Please understand that these are items stored at home before purchasing. Will be reinforced with cardboard and placed in a plastic bag for shipping. Instant purchase is welcome. Please refrain from price negotiations. Mushroom encyclopedia Sticker Craft sticker Fly agaric Caesar's mushroom
