Here is the inside of the shed with most of the boxes inside. I stacked them 11 boxes high.
I used to put label tape on the boxes, but it is too small to read from six to ten feet away. The simple 3 X 5 cards seem to be cheaper, and easier to read.
This is a close up of one of the weight stickers. Lightest boxes on top. CAC is Coast Artillery Corps, US Army, WWII era. Can you identify the Roco 155mm Long Toms inside the box?
