K-1 sent me a poster from the last (probably) K-1 Finals (2010), signed by all the fighters that took part that night. Overeem, Aerts, Schilt, Saki, Ghita etc, etc.
It's a big poster, but was sent from Japan in a smallish envelope rather than a tube, so it has been folded twice and is creased in places. Still, there's no actual damage and it'd look fine in a frame or after being flattened out under a rug for a day or two.
I don't have anywhere to hang the bloody thing, and I think it's criminal that it's sat unappreciated in my store cupboard. If anyone is interested, please make me an offer!
