What is your primary area of focus for your autograph collection

[markf31]

I'm quite new to collecting autographs, but when I collect I like to define a focus of my collection, a goal, or a topic if you will. I also think it's cool to hear about the focus or topic of other collectors collections as well, so please feel free to share! Or perhaps you don't have a focus and you're just all over the place.

As for my focus I'm working towards autographed balls of HOF pitchers. I thought, what better way to assemble a collection of HOF pitcher autographs than on the tool they used to ply their trade with.

My goal is to obtain an autographed ball from each league commission the player played under. So for example, with Warren Spahn I will eventually like to collect a National League ball signed by Spahn with Commissioner Ford C. Frick and another with Commissioner Warren C. Giles
