Martin Cooper autographed glossy color 10 x 8-inch photograph depicting the pioneering American engineer holding an early Motorola handheld cellular telephone on a New York City sidewalk.

The photograph commemorates April 3, 1973, when Cooper made the world's first public call from a handheld cellular telephone while working for Motorola. The historic call, placed on a prototype device, marked a major milestone in the development of modern mobile communications.

He has additionally written, "John was my boss & mentor," referring to Motorola executive John F. Mitchell, who played an instrumental role in the development of handheld cellular technology.
