Here's me and my mom assembling my first "real" LEGO set (as opposed to Fabuland). A castle wagon. In the backgroup, however, are those same square stickers from the shoebox. I'd gotten them for Christmas and plastered that desk in them. I am 3 in the picture. I am 99% sure that my brother had the Darth Vader shoes from the ad and that's why the box/stadnup figures seem so strangely familiar.
If I could find more pics of the same Christmas I know several Star Wars toys would be visible
