BIRDS' EYE VIEW... The rest was left blank, but card back offers a wealth of info. Sender was because of TB affliction "... THIS PHOTO IS OF THE SANITORIUM AND WAS TAKEN FROM THE TOP OF THE MOUNTAIN BACK OF THE HOSPITAL..." MONT ALTO, PA. STATE HOSPITAL 1916, with matching postmark. Magnifier reveals main building plus many smaller units, probably to keep patients isolated. HISTORIC card has some corner wear. Shipping is $1.50. Thanks!!
