Lousgard for Lice & Mites Vintage Unopened early 1900s advertising veterinary

Description

Pictures will tell best the story and description of this rare Lousgard concoction.  It appears to made of hard cardboard-type construction and has survived the years very well.  The graphics on this date it back to early 1900s in my opinion.  It is undated and I will let you make up your own mind about its age.  It is full and unopened.  The holes on the indicate that, to use it, you would twist the lid to free the paper from around the rim of lid, then turn to where the holes allow the powder to be shaken out onto the targeted livestock.  Obviously, this is sold as old advertising collectible and definitely not for the original purpose.  Ingredients are shown in the 7th pictures.  Thanks for viewing.
