I have owned this Ron Evans signed postage stamp document for the last number of years. It is a patent document for a device for amplifying feeble electrical currents by L. De Forest with a stamp affixed which is postmarked New York July 10, 1973.I know some people like to have personal items signed and I am aware that Evans was an electrical engineer but I would like to find out why this document could be related to Evans (if any) and if there is any value associated to it apart from the value of an Evans signature.

I don't know if this helps, or even if it is related, but one of the cachet themes issued for the 1973 "Progress in Electronics" stamps was "From Spark to Space" and the set was issued to commemorate milestones "from Marconi's turn‐of‐the-century spark coil to the transistor that set the stage for the Space Age," as The New York Times reported on July 1, 1973. The stamps will make their first appearance in New York City on July 10, the fourth anniversary of man's first step on the moon. I have tried to find a report from the first day of issue ceremony to see if Ron Evans was among the guests, but the closest I have come so far is a scan of the program cover. I also found this eBay listing with the same patent sheet, stamped and signed in the same way, but with Roy Dolby's autograph. | |
