This is a really fun vintage Jello Box. It has the lid still attached to it, which is rare. 14 inches wide x 7 inches tall x 8 inches deep
 
Jello was invented in 1897 and still continues to be popular over the last 125 years and no signs of stopping! 
 
The Jello graphic on the side is also prominent, and it’s so fun to imagine that this was how stores received their product to sell way back in the day.
 
We don’t know the exact age, but I would say this is likely 1920s-1930s era.
