According to its registry page at the Professional Sports Authenticator (PSA) website, there are 55 cards in this set. It was released in 1966 by Topps. I only have two of these cards. Here they are:
Card #9 Front
Card #9 Back
Card #41 Front
Card #41 Back
Interesting idea to meld publicity and production photos with an ongoing "story" on each card. The second photo was taken from the "Welcome Stranger" episode [10/20/65]- with guest star Warren Oates as "wandering astronaut" Jimmy Hapgood- where, at one point, Will fails to keep spraying Hapgood's capsule to prevent alien spores from growing around it. One of the humongous plants almost winds up "eating" Penny!
