Every Goldberg Buster kit I've seen has been in a long, thin, white box with a small black and red printed label. The Shoestring and Cosmic Wind were in shorter, fully printed multi color boxes. The reason for the different boxes is that the Buster had one piece, full length leading and trailing edges, while the others did not. I think all these kits hit the market in the mid '60, perhaps not all at once. The Shoestring in the plain box with the small label didn't come out until the other two kits had been discontinued. This may have been 1990 "ish".
