1941 JULY 16: MANILA to ROTTERDAM
Court of First Instance official mail endorsed VIA CLIPPER, bearing 12c x 2 Salt Spring O.B. issues mixed with 5p George Washington small "COMMONWEALTH" issue for 5p-20c Quintuple Air Mail Rate overpaid by 4c). Redirected to BERLIN, received August 17 and by the U.S. Embassy the following day. 

Philippine postal rates for 1939, valid until 1941, made no mention of air mail rates to Europe via the U.S. Since the above cover is endorsed Via Clipper it is assumed that the postage paid is proper as PanAm, beginning 1940, was flying to Europe three times a week. 

VERY UNCOMMON MIX FRANKING
