This is a postcard published by Mary Jayne’s Railroad Specialties out of Covington VA. Printed by Alleghany Publishers, Covington VA. Photo by George E. Lawrence (no relation). MJRS published a series of cards on aircraft. I think there are around 200 different cards in the series.
Anyway, Aerostar was owned by Professional Travel, Inc. of Louisiana. In 1981-82 the company was expanding. In 1982, they secured permission from the Civil Aeronautics Board (in existence from 1938 – 1985) to set up the airline and eventually secured three 727s from Eastern Airlines. In 1983, it was all over. Eastern repossessed the aircraft and the company went bankrupt. The name Aerostar has been used by an airline out of Kiev, Ukraine, since 1995.
