The listing, Vintage Edison & Electric Light First Day Covers has ended.
These are two first day issues from Greenfield Village outside of Detroit, MI. 1968 and 1979. The Henry Ford stamp, and the anniversary of the electric light, with special cancellations from the place that has his birthplace. Stamps and cancellations. There are some waves in the envelope from age, but likely these can be pressed out with a telephone book or other heavy book. A great pairing, perfect for any collection.
