Spring 2023 Mail Sale Commentary 

Lot 3 L102 — Viking Mission to Mars (7-20-78)

This is the extremely limited L102 cancel variety with only 40 in existence. A plate number single has the bullseye first day of issue postmark from Hampton, Verginia. I then drove to  the Outter Banks and obtained a Kitty Hawk first day postmark with killer bars. I believe this is the first time this limited cancel varity has appeared in one of my sales. This is a seldom seen opportunity to obtain a very limited cancel variety Collins cover.
