This is "A letter from the mental hospital" [first entitled "Industry"],
which is installed at the Hygienic Arts annual Salon des Indépendants
now on exhibit in New London Connecticut, this year, from 28th January through 11th February.
In changing the name of this collage, it provides a more accurate reflection of the source of some of the materials; in particular, the upside down letter ~ framed by two oxidized kitchen knives, were among artifacts I came across when urban spelunking at an abandoned insane asylum. The building had not house people since the 1970s. The letter was from a woman to her family, asking when they were coming to visit and wistfully talking about coming home. Obviously, the letter never got to the intended parties.
Below is one of the posters for the show, painted by artist Glenn Hart.
