Lunchboxes have changed in design and shape over the years, but the basic idea is the same: Along with space inside for a cold drink, sandwich and snack, the cover is devoted to a favorite cartoon, character, TV show or movie.
That's why Justin Bieber, Darth Vader and Japanese cartoon characters are staring out at shoppers from the shelves of Target these days.
Back in the '70s, the lunchboxes were aluminum. In the '80s, they gave way to plastic.
Vintage lunchboxes now are highly collectible. They are displayed as collections in people's homes, and sometimes get their own art gallery shows. (Yes, I've gone to one.)
