Tremendous fold-out postcard mailer featuring the 1910 Chicago Cubs on the interior pages an outstanding action photo picturing Johnny Evers stealing home - and sliding high and hard - on the front cover. Folded the card measures 6 1/2" x 5 1/4" held together by a tab that tucks into a slot on the mailing side of the card. Opening the card yields a large strip of side-by-side black and white photos that somewhat resemble E121 cards though slightly larger (each of the two-photo panels measures about 5 7/8" x 4 5/8"). As one would expect years of being folded inside has caused some of the thin paper photos to weaken considerably at the folds some becoming detached or barely attached to the adjacent photos. Exercise caution when opening this! The outer card printed on much heavier stock has been reinforced at the top edge with clear tape at some point. Some paper loss and overall wear is evident though not distracting. FAIR condition but an excellent piece.
