Produced by one of the hobby's first publications, The Trading Post, the Spots Exchange "Baseball Miniatures" were distributed in three series, in sheets of six, with each "card" surrounded by a green, red or gold border, with each color representing the series to which the cards were issued.  Part of the red border series, this sheet is the key to the entire group, including Babe Ruth, along with Hall of Famers Jimmy Foxx, Hack Wilson and Rogers Hornsby, along stars Luke Sewell and Lefty O'Doul.  With a clean front, the piece presents as EX, though the technical grade is reduced somewhat due to age-related discolorations at the reverse, perhaps due to long-ago scrapbook removal. Measures approx.7" x 10".
