Photo and negative from my collection.
Author: Herbert Heller.

Many photos are still taken at the same spot by tram enthusiasts today.
However, there was no tram museum or any other activity in 1969.
The trams in the photos are not P.C.C.'s, but both are rebuilt four-axles, which have been given a new (P.C.C.) body.
Both trams still exist: one of them ended up in the museum as a work tram, the other is reported to still exist in Canada, although its fate (now: 2023) is particularly uncertain.
