Well, hopefully everybody's worked off their post-Thanksgiving torpor! Assuming so, I am looking for a little help today. 67 years after it came and quickly went, the 1955 Topps Hocus Focus self-developing issue remains a thorn in my hide, at least in terms of completing the full checklist. To refresh your collective memories, Topps issued the set in two sizes, a 96 subject affair known in the the hobby as "Large" and a 126 subject nightmare similarly dubbed as "Small" with the size of the card dictating, i.e. the Large cards measure 1" x 1 5/8" while the Small ones clock in at 7/8" x 1 3/8", which was the same size as the first Topps Magic Photo cards from 1948, which used a similar process to develop the images.
When I published my book covering Topps in the years 1938-1956 a decade ago, I realized that the checklists for both sizes had been hopelessly co-mingled and set about to extract one from the other. It turned out the first 96 subjects in each size were shared and that Topps had issued an additional 30 cards in the smaller size, which were unique. They took five of the subsets and added either five or ten cards for this "extended" 30 card series (I hate to use the term high numbers here because the last 30 Small cards exists in the same numbers as the first 96 in that size). This numbering scheme has caused confusion since 1955!
Look at Johnny Schmitz's two cards here. The 1955 (Small) has four imperforate edges, since they were only issued with penny tabs of gum, inserted between the inner and outer wrapper:
Note the number in the black circle at bottom right. That's the overall set number for Schmitz, where as the Photo No. 18 of 23 Baseball Stars represents his subset numbering. So he is 84 of 126 subjects in the Small Hocus Focus set. The Large size Schmitz is identical in appearance on the front...
...while the reverse shows the score lines used to separate one of the large cards from another as these were issued in panels in five cent packs. In addition, the subset numbering of 16 of 18 has been altered to reflect the smaller number of Baseball Stars issued in the larger size, while the overall set number remains at 84, in this case 84 of 96.
