The 1888 Yum Yum tobacco set is obscure and extremely rare, issued by A. Beck & Co. out of Chicago.  George "Piano Legs" Gore was a fine batsman for the Chicago Nationals from 1879-1886 but ended up with the Giants in 1887. There are but two examples in the SGC pop report, this one and another that's graded VG/EX 4; PSA has none registered. The obvious issue is the drawn circle added to the front, and the upper left corner carries a stain that shows through to the reverse.  The image is a bit light but with the lack of available cards, it's a desirable example despite the flaws.
