[CIRCUS POSTERS]. Strobridge Lithograph 1910s-20s circus poster photograph archive. Approximately 80 pieces, silver prints and halftone cyanotypes generally printed or mounted on cardstock (size generally 5 x 8?). A RARE surviving photographic record of posters from the period, each card reproducing the poster image and generally recording the size (e.g., 1 sheet, 3 sheet, etc), year of printing, title, and inventory number. Likely contains images of posters of which no physical examples have survived, in particular billboard-sized posters.
