A friend of mine found an 80's era Stros cap at an estate sale in Wisconsin. He got me the cap and it has two signatures inside that look like "Nolan Ryan' and "JR Richards'. Can any of y'all more knowledgeable about Astros memorabilia tell me if these might be authentic autographs?
Don't know if it helps you any, but here's a picture of Nolan Ryan's signature on a ball that I bought from his foundation in Alvin in the 90's.
