It was interesting for me to see that several of the promotional pictures on the box were obviously taken from the VIC-20 set of promotion pictures. The photos of "users" show a VIC-20 (identifiable both by colour of the computer and also the screen ratio and character size). The peripherals shown with the actual C64 (bottom photo) are all "VIC" ones and the "artists depictions" of the games are the same ones as from the back of the VIC-20 box.
Of course, this all makes sense as the C64 was so new at this time that the Commodore art department probably only had VIC-20 images to use - and the peripherals (i.e. 1541 drive) hadn't received the updated colour scheme and rainbow label yet).
An interesting but small historical footnote. Here are some photos I took of the box (click on any to enlarge):
Interesting also is that in the photo with the kid, above, the datasette looks like a black PET version. This would make that photo a very early one from the first days of the VIC-20 (before Commodore matched the datasette to the VIC-20's white case).
