I've recently moved home and I am currently in the process of finding old stuff and chucking it out, as you do. I've found loads of old skateboarding stuff from over the years, some of which may be of interest.
This is an old sign I've had since I was about 15, it is from a church (no shit) in south Belfast we used to skate. They must have put up about 4 or 5 batches of these within a year! There were a few up at any one time and they all got nicked. I may be the only person to still have one of these. The church eventually realised that the signs would keep getting stolen so they resorted to spreading gravel everywhere and thus ruined a nice wee spot.
