Expose yourself to art

[garote]

One of my absolute favorite comedy shows is The Young Ones. It first appeared in 1982 and made its way to my living room in 1985. Surreal, manic, highly destructive, puerile, kind of loathing youth culture... Basically my personality at the time.

A while back it finally, FINALLY got a Blu-ray release. In the first episode you can see a poster on the wall for a few seconds, and now it's visible enough to make out details:

The photo on the poster was taken in 1978, by a fellow named Mike Ryerson, in the Goose Hollow neighborhood of Portland, Oregon. He originally intended to make it a poster for the Venereal Disease Action Council, until a reader of The Northwest Neighbor newspaper wrote in and submitted the caption "expose yourself to art".

How in the bloody hell did a photo taken in Portland end up on the set of the first episode of The Young Ones four years later?
