At a usually dismal flea market in the northeast, I bought a very neat 1930s scrapbook from an old lady vendor for $15. I usually don't do scrapbooks but this one was pretty nice and then I saw a Cab Calloway autograph in there, on Cotton Club stationery. SOLD!
It was only when I got it home that I discovered the Babe Ruth-signed 1936 World Series ticket. Sold that page at Heritage a few years ago, to a disappointing result. So it goes.
