A patent print poster of a Multiple Electrode Vacuum Tube invented by Frank Conrad for the Westinghouse Electric & Manufacturing Company. The patent was issued by the United States Patent Office on April 16, 1929. In electronics, a vacuum tube, an electron tube, or colloquially a tube in the US or valve in the UK is a device that controls electric current flow in a high vacuum between electrodes. Frank Conrad was an electrical engineer, best known for radio development, including his work as a pioneer broadcaster. He worked for the Westinghouse for 50 years. His experimental radio station provided the inspiration, for the establishment of Westinghouse's first broadcasting service. Conrad was awarded more than 200 patents internationally throughout his life.

WHAT MAKES OUR PATENT PRINTS DIFFERENT
You won't find any Patent Art like these. I carefully select each patent for its historical and artistic value. Often, various sections of the patent document are assembled into one beautiful print. I also painstakingly remove most imperfections and flaws in the original document and do extensive digital restoration while maintaining the integrity of the original patent. This will make the print crisp and clear - almost like the day it was filed. I don't use regular printers and paper to print this art. Instead, I use a high end lab and the prints are made on professional photo printers using high quality a archival inks and acid-free archival Lustre paper. Lustre is a premium finish on a heavier paper and offers the vibrant colors of glossy with the fingerprint-resistant finish of matte. This avoids glare on the print.
Prints are packaged to avoid any damage in transit. Usually prints will be flat-packed (not rolled) and shipped in a rigid box with material to protect the finished print. Some larger prints will be shipped in a rigid mailing tube with material to protect the finished print. Please see the shop's policies page for additional information on shipping.
