This was one of my favorite non-baseball card Ebay pickup of the last few years. These post card sized cards from the Theodore Presser Co. were sold to music teachers who gave them as "rewards" to their students. The cards are hard to date exactly. The seller said they were between 1908 and 1920 but they may be a little later. One fairly sure thing is that they are pre-1949 when Presser moved from Philadelphia to Bryn Mawr. I bought all eight cards for $2.99 shipped.
