Today I found in a "Sports Reviews Baseball" from 1955 with a full page shot of Herb Score, holding up for the camera...ta da...his Herb Score HSP Rawlings model.
(inside palm shot) This was the last Rawlings top-line glove of the "cupped" series. An elongated version of the HH. Rawlings went to the XPG and TT series for their best gloves afte this one.
