Original U.S. Letter Patent certificate from 1977. For a Energy Efficient Bi-Radiant Oven System. This has a historical name of Lutrelle F. Parker, who was the first African American to serve as commissioner of Patent and Trademarks. I showed most of the pages but there a few more as Ebay only allows 24 photos. I purchased this from the person who created this invention. Excellent condition and was originally framed. This will weigh 1 lbs with packaging and comes from a smoke free home.
