Nice pick up Gary. I'd like to see a close up of the label — they often have a story to tell. I get my best photos of caps outside in the shade.
Here's a few caps I just picked up from the recent sale of KM Pro's archives. Included are two 1-year caps: a 1970 A's cap and 1971 Angels cap., along with some kind of A's prototype from 1968-69. Also, here's a link to a blog that features an interview with Paul Kaufman, whose father partnered with Tim McAuliffe to create KM Pro.
