Color 8 x 10 NASA photo of Armstrong in his space suit, boldly signed in black felt tip. Accompanied by a 1972 secretarial letter of transmittal on NASA letterhead. The very subtlest suggestion of handling wear (a few minuscule dings and marks to background), otherwise fine, clean condition. As Armstrong often signed with a pen that contrasted only moderately or tended to fade over time, the oustandingly dark and clear signature on this example is especially noteworthy. An unusually appealing example of this most coveted of Armstrong formats! R&R COA.
