Postmarked 1913, the card has a trademark TB in a circle. Could be an early Tichnor Brothers who began publishing in 1912. Seven years later, the 18th Amendment was ratified, no doubt because of folks like this!
"A Part of what goes on within the Famous Hot Springs Bath Houses"...I'm not really sure what IS going on here, but I think this is one strange postcard. Makes me think more of an asylum that a spa. The backs has the saying, "We Bathe The World"
