vtg skateboard photo polaroid - Signal Hill speed run 1970s historical

Up for auction is a vintage skateboard photo polaroid, candid shots. All from the 1970s era, these are from the Free Former World Professional Championships and the Signal Hill speed run of 1976, 1977, or 1978. I believe they are mixed from these years, mostly from 1977. And most if not all of these particular pictures are from Signal Hill. You get ONE photo, you choose which one from the drop down menu. In pictured condition, all of them are in pretty good, with some color fading from age. A ll from the early days of modern skateboarding, these downhill speed contests were a key part of skateboarding history. Lots of new companies and products debuted here at this contest, tremendously dangerous for the skaters brave enough to do the run. These are unique shots of iconic moments in skateboard history from the contest that was billed as the first X games. These all came from Powerflex, Bob Ballou (who ran Powerflex). The edges of the item, where the diagonal color bars meet the vertical and horizontal edges measure inches, roughly. Feel free to ask me any questions you need to know and I will definitely hit you back with my best answer. Good luck, and enjoy!
