A small tin litho viewer for 3 in. stereoviews manufactured by The Metropolitan Syndicate Press of Chicago. There was also an entity in Chicago around the same time called The Metropolitan Press Syndicate, which was owned by Sears and printed their catalogs. I haven't found anything about the relationship, if any, between the Syndicate Press and the Press Syndicate. To add to the mystery, the president of the Press Syndicate was Prosper Dalien Fenn (Hoosier State Chronicle 1909, p. 1), who received a patent for a collapsable stereoscope, somewhat different from this one but with a similar container to hold multiple cards in a box attached to the viewer (Fenn 1906). Also puzzling, a virtually identical viewer called the Colibri was manufactured and patented in Germany by an unknown company around the same time (Wangari 2026b).
