I have the Dealer Price List from 1961 for the Zeiss Ikon portfolio. This 34 page document contains everything from the Bullseye, to slide viewer to Contax IIa and IIb, slide projector and even their moviscop editor! It even contains the graphic line drawings and descriptions for each of the Bullseye's lenses. The brochure is in excellent condition and I have the original mailing envelop. Asking $10.00 which includes shipping in CONUS only.
