WTB Ellis Animated FDCs

I am a serious collector and eventually (hopefully) an exhibitor of Ellis Animated FDCs. These were created by Richard Ellis. I am especially looking for any Ellis Animated from 1967, 1968, and 1969. I am also looking for almost all Ellis Animated from 1982 and later. Because Richard Ellis (the creator of Ellis Animated FDCs) was a space enthusiast he also created event covers for many space events such as Apollo Launches which I would be interested in, as well as any other unusual Ellis Animated covers. Thank you.
