I've certainly posted about this before, but I collect the signatures of all pitchers that have thrown a no-hitter or perfect game from 1893- present.
Currently I am still looking for less than 20 signatures.
A few of these signatures are either out of reach price-wise (Christy Mathewson) or are likely not findable/ affordable (Addie Joss).
The remaining names on my want list are players that are seldom seen or I haven't been fortunate enough to find- yet?
