Back when people gave a damn

Here a picture I found on the electronic ether of an old box of dynamite from the 1920's (why was I searching for pictures of Hercules? For work. Honest!). Except that rather than just stencil "dynamite" or "boom" on the the box, some intrepid soul thought long enough to come up with a concept that would differentiate the product from others in the munitions aisle, and then showed admirable restraint in delivering a nice little graphic reward to those dynamite shoppers with discerning eyes.
