Auction # 2044 WORLDWIDE + ARGENTINA: General October auction

POSTAGE ERRORS: 2 Covers sent to Belgium and England on 29/FE/1928 on FIRST FLIGHT by Aeroposta, the cover to Belgium is franked with 12c. for regular rate and 3.35P. for the airmail fee (it was probably a 18 gram cover, so it was overcharged by 11c.). The cover to England had an inscription in pencil "72" possibly indicating the airmail fee for a 4-gram letter, the 12c. for the regular rate is then missing. Very fine quality, interesting group!
