The caption on this unused , aging real-photo card tells us this aircraft at the time was operated by Olley Air Service Ltd., in Croydon (U.K.).  A little Googling leads to a later photo and this information:  “ex-Shorts Brothers Dove 1 with Gatwick-based Sky Charters, which ceased operations in August 1965. G-AJOT was sold in July 1965 and became 6V-ABL in October 1968.”  We know it then went to Air Senegal but have not tried to follow the trail after that.  Significant foxing on the reverse.  Grade: 3
