BOLETÍN FERRARI: The first 3 issues of this very rare publication (October and November 1929, and September 1930), with interesting articles on philately, etc., mixed quality (from defective to very fine), possibly the only set in existence of the first 3 numbers! (Image)

VERY THEMATIC LETTERSHEETS: About 30 letters of early 1920s hand-written by a traveling salesman that traveled around several cities (in the provinces of Buenos Aires, Santa Fe and Córdoba), all with fantastic commercial letterheads, most of HOTELS, also furniture stores, restaurant, drugstore, etc., almost all of excellent quality, good opportunity!
