This card is inspired by the TV series. Each is printed onto brown cardstock in shiny metallic gold foil on the left hand side. It's very hard to photograph the gold foil. Any variations in color you see are items reflecting in the mirrored surface. On the right, is a gold foil print of the inside of the Farnsworth communicator with a custom photo. Each measures approximately 5.5 x 3.75 inches and comes with a black A2 envelope. The inside can say anything you like up to about 50 words. Please email the photo you would like us to use after placing your order. We recommend getting a gold metallic or gel pen to address the envelopes (not included). You may order in sets of 12 to use as invitations or save the dates. The gold foil process is not perfect and there may be tiny areas of black showing through occasionally.
