Box art is by the famous Jo Kotula who did 1930s covers for the magazine 'Model Airplane News' and later the Aurora box art of the late 1950s. Air Lines kits are all Frog molds that the Lines Brothers imported to the USA between 1964-1966. The kits, decals and instructions were made in England, then imported to the USA where Testors created the boxes with the colorful trading cards on the back. There are one or two trading cards on each box which show the boxart but not the advertising/logo.
