Also from the same site and page as above, if you don't have one of these stamps your box is before 1917 which I think your box may date that early.
So from the printed "Caution Notice" that you posted an image of and mentioned in my previous post and your box seemingly not having the Tax Class stamp, your box appears to date between 1910 and 1916
I'm haven't trouble copying the images from this site along with the text so I've copied the text and you'll have to visit the page to view the stamp images.....
After 1917 a Tax Class Notice is required to be on the front or bottom of every box for the next 50 years. There’s no easier way to tell at a glance whether a box is before 1917 or after 1917. Golden Age boxes don’t have tax paid notices. Machine age (1917-1959) boxes do. Modern (after 1960) boxes don’t.
if a tax class notice is pasted on and does not mention the price of the cigars, it dates 1917-1919. If the tax class notice is printed on and gives a range of selling prices, it dates 1919-1959.
OLD ABE is a very typical 1920’s box. You can see the Tax Class Notice on the right and the orange on blue tax stamp (1917-1942) on the left. Front or bottom, if there’s a Tax Class Notice on the box it can’t date before 1917.
