A pair of small (4 x 8.4 cm including the barcode bit, 4 x 5.5 without) vinyl stickers I found among old papers. I'm sure these came with something? Or were they associated with the 2004 Unholy Alliance date in Helsinki I attended? I recall hovering at the merch stand for a bit and purchasing just a T-shirt. The barcode seems to refer to a flag... one of my friends had a big flag of this in the 90's but these can't be that old and why would I have them?
Anyways, neat little stickers, might cut the barcode bit off and use one somewhere.
