The photographs for postcards credited to Pablo Sittler were taken in both black and white (called real photos, or RPs) and color film (called chromes) in the 1960s and 70s. Bearing Sittler's own imprint or that of Foto Europa, some of the RPs have deckle, or uneven, raggedy edges, and their numbering system runs to at least 118 images. Other RPs have straight edges, white borders, and titles but no numbers. Many titles for the RPs and chromes are printed in dual translation.
The Lito B. Zadik Company published full-color photographs in a standard size of 3-½" by 5-½" that the company credited to Pablo Sittler. The cards bear a printed price of 5¢. Other photographers for the Zadik company are featured on the following page of this site.
