Here are a couple more ads. The earliest ad I have seen is 1917 and it shows the label a little different, with "Boys" at the top. These ads are drawings and they may or may not have ever printed or used this label.
The wood boxes had 1 #0, 4 #1's and 1 #1 1/2, along with the "The Boy Trapper's Guide". The first boxes had the sliding lid and then a nail on lid on the latter ones.
The cardboard box came with 1 #0, 3 #1's, 1 #91 and 1 #1Giant, along with "A brief Guide to Trapping".
