Wallet Card with a Deadly Disease

I noticed some empty spaces for advertising posters on Track 18 at Penn Station. I've had surprisingly good luck with really old flyers that have been hidden underneath ads, stuck on for good with adhesives that are no doubt banned today. This one is a weird one.

Not much to go on but just a hunch that these were old. I actually was thinking they were probably just modern rat poison warnings, but it's actually more interesting.

While there's a lot to dislike about modern Google search, one great thing is that Google Images now automatically searches for text in photos, not just in the website the photo is on. I tried googling "Deadly Disease Stay Away From", with no luck in the regular results but a perfect match in Images.

This is a photograph by acclaimed photographer Louis Clyde Stoumen, called Deadly Disease, Times Square, New York. There are copies of the photo in the museums of Amherst University, who date the photo as 1980, and Duke University, who date it 1978. 

I couldn't find any more information about who was posting these flyers about tuberculosis around New York City in the late 1970s or early 1980s, but it's cool to know that at least a little bit of these 45+ year old amateur flyers are still visible today.
