Complete block of forty 32-cent "Computer Technology" postage stamps, signed across the center in black felt tip, "Doug Engelbart." In fine condition. Accompanied by an unsigned example of the same stamp sheet.
On October 8, 1996, the U.S. Postal Service issued these 32-cent "Computer Technology" stamps to commemorate the 50th anniversary of the unveiling of ENIAC (Electronic Numerical Integrator and Computer) and the pervasive influence of computers and computer technology in modern life. The stamp's graphics-pixelized PCBs over the outline of a human brain-also act as a fitting tribute to a founder of the field of human-computer interaction, Douglas Engelbart.
From the collection of Bill Daul, a longtime friend and colleague of Douglas Engelbart.
