For sale is an authentic hand signed GERALD CARR 8x10 color NASA photo. It is inscribed To Mark. Photo is in terrific condition, much nicer in person and will look great once framed. Signature is 100% authentic. Shipping for this photo will be $6. Sorry I only ship to customers in the USA. I package very well with cardboard for protection.
