Some old Maisto card backs.
I don't know this early history but it looks like someone got pressings from the same molds that Road Champs had used...which had Lintoy origins...and brought the line out. Later they expanded and gave itself the name "Maisto" and I believe this to be the May Tat Toy Products. It was May Tat who would own/operate as Maisto until just a few years ago, when production would falter and then, end - at least of the aircraft - as a new owner took over.
Currently there are Maisto Tailwinds on the "mass market" out there. Losing order from WalMart for this product must have hurt.
