Classic NASA 8x10 WSS litho of Jim Irwin handsigned by him – bold clean signature guarantueed to pass Zarelli authentication ! (if not we will refund all costs !).
Irwin NASA WSS lithos are among the rarest of all signed space photos as he didn't like that shot and rarely signed item. Uninscribed examples are selling up to $10000 already with only a very few having surface on the market in the past 25 years.
