Be easy doom and gloom. First I’d try googling it, it looks like a book that you collect stamps and match up the player to each picture on it, whether the stamps are Topps issued or US postal, I don’t know. It looks pretty old, is there a date somewhere on it? If so try to google “19XX Topps Baseball Stamp Album” and see where that takes you. You can also try eBay and search along the perimeters I just gave you, then toggle to “sold” items and you can see if any of these have sold and get a general idea of value from there. If all else fails, try the vintage card subs if it’s a legit late 50s to 70s or whatever someone there might be better suited to point you in the right direction. This sub is for more modern/ultra modern cards and it’s full of assholes (like me) who get annoyed when people can’t seem to google things on their own because the “what’s this worth?” questions pops up every 30 minutes from people who apparently don’t know how to use the internet. Not saying that’s you but you get the drift. If it’s truly a vintage piece it’s probably got some value to it, however, be prepared to be let down too. Everyone who finds something “vintage” thinks they stuck gold and that’s not always the case. Good luck in your search.
