"Honoring DeKalb's Inventors" envelope

This commemorative envelope, distributed by the Land of Lincoln Barbed Wire Collectors Association in 1974, honors "DeKalb's inventors."

Isaac Ellwood, Jacob Haish and Joseph Glidden are portrayed on the envelope to advertise the Barbed Wire Centennial. Although the Land of Lincoln group was later disbanded, many of these commemorative envelopes (in various designs) are still floating around today. I recently posted about a Haish design here.

Thanks to Rob Glover, Glidden Homestead executive director, for sharing this with me.
