Vintage Hercules Powder Dupont Letter Opener and Advertising Card

Vintage Hercules Powder Dupont Letter Opener and Advertisement Card
I was looking for another item to post for the 4th of July Weekend.
This is the closest I could come to fireworks.
I'm not much of a fireworks fan.... I see a couple go up.... ooh ahh .... then I'm pretty much ready to go home.
I used to help my dad blast stumps on the farm..... blasting with more of a purpose... IMO.
Again..... Happy 4th! Be Safe.
BTW..... the stick of dynamite pictured is theater prop from a case I purchased a few years ago. :)

Thanks Much for Looking at my Post!!
