D380 was an obscure set with its 21 cards depicting players of the 1910 Rochester (NY) Bronchos, the class of the Eastern League.  Known more as "Pat", Don Carlos Patrick Ragan (yup) had a long pitching career in the pros, with 11 major league seasons among his total of 17.  This is a typical example for the grade, with various creases and notching of the top border seen. The reverse appears to have never been album mounted. D380's are extremely scarce and almost never surface.
