These cards, "World Air Forces" "Mach Series 30 Models," were purchased nearly 50 years ago (likely in the 1970s). The size is 26.0cm x 17.6cm. The manufacturers are listed as "Onda" and "Koyo Co., Ltd." I don't know how many cards were released in total. This is a set of 10 types, 11 cards. * VOUGHT A-7 CORSAIR II * DASSAULT-BREGUET/DORNIER ALPHA JET * DASSAULT-BREGUET MIRAGE F1 * LOCKEED SR-71A * MIKOYAN MIG-21 * McDONNELL F-15 EAGLE * GENERAL DYMAMICS F-16 * LTV F-8 CRUSADER * SAAB AJ37 VIGGEN * SAAB J-35 DRAKEN There are two "SAAB J-35 DRAKEN" cards.
