H.W. Carter & Sons, Carter's Overalls Receipt Envelope

I recently picked up this piece from my friend and vintage dealer John Gluckow of Strongarm C & S Co. it's a H.W. Carter & Sons, Carter's Overalls, receipt envelope from Savard & McCarthy Clothiers in Kingston, New York. There's no year date on the envelope, but I'd place it from the late teens to the early 1920s. Joseph Savard and John E. McCarthy teamed up in March of 1915 to form the firm of Savard & McCarthy. At the time Savard owned eight other stores in Connecticut and New York.
