Thank you Dave! Assuming that the photo is real, this is a gold mine of info for me. Anyone familiar enough with the 55 Topps set can probably name every card by sight even in this resolution. Off the top of my head, I see a lot of low number cards, Billy Herman, Rhodes, Aaron, Kaline, maybe a Ted Williams bottom left? Pretty sure I see a monte irvin, 100, third row center. Sandy Amaros on top left? So this is definitely a first series sheet.
I'm pathetically excited right now, like I just spotted Bigfoot

Thanks for making my day.
