We wanted to have a load of items that we could throw around foxholes and camps like rubbish, so the areas would have a "lived in" look. I came up with this booklet of period-correct food can labels.
 
There are over 20 labels included and they look amazing, all professionally printed on high quality paper. Each label is slightly larger than a normal can, so these should fit a wide variety of cans from various nations. Even UK food cans and pet food cans vary in size slightly. Just cut these to the appropriate size for each can.
 
Kept the price as low as possible, but retained the high quality - I think I found a good balance!
