The 1903 E107 Breisch-Williams Baseball Card Set contains 103 cards measuring 1 3/8" by 2 5/8", and these cards can be hard to come by due to their original regional distribution in Oxford, Pennsylvania. These cards can have one of three different backs, with the most scarce being one the name of the company on the back.
While all of these cards can be scarce, the most difficult card to find from this set is Honus Wagner, which makes a complete set nearly impossible to complete.
