Bob--I am working on something really snide to say but need more time.
Great stuff. Are you sad to be at the end ?
The only other Topps Ryans I have are the 82 Blackless and 85 Minis, blank back and regular back. My blank back in a white back. It can be found in tan. I have many cards in red only backs ( no green ink) as well. I assume the Ryan can be found that way, but I have not seen it.
I think the rarest Topps Ryan is his appearance in the NL Game 3 that is part of the limited 1970 prototype Cloth set. It looks like the regular card but is cloth with a sticker back. I have only seen one, owned by a sometime board member. I only have one of the 70 Cloth " cards"
