A probably unplayed splatter-vinyl copy of Led Zeppelin's 'Riverside Blues' on the European Swingin' Pig label. This copy, numbered 29 of 250 on the front cover sticker, features a color front cover picturing three Zeppelin members with Fairport Convention singer Sandy Denny (who guested on their 'The Battle of Evermore.') The disc is mint, the cover near mint with a 1 ¾' split to the top center seam.) The only copy we've ever found.
