Pocket sized dance card, double folded, 6x4" open. Outside as shown in photo at upper left, dated April 17, 1918. Inside lists 20 dances (Fox Trot, One Step, Waltz; and four "extras"). The first 6 dances are trapped in ink to an "Evelyn Weil". Included is an invitation of another dance, the "Aerial Ball" on Sept 14, 1918 (shown below in the photo at left). All very good or better.
