Sears Airline Reservation Computer playset
There is no question that I love unusual toys and I've never seen this!
Was this for the Wonder Woman line? In one of the pictures, there is a box marked Top Secret so this couldn't have been used for the Barbie line.
It was never for the Wonder Woman line, it's just a generic doll playset that Sears sold. The sole connection to WW is that Sears sat her in it for the catalog shoot.
I kind of want one to customize, I love that computer.
