I was a student pilot in 1971 and attended an air show at Brewster, WA and
took these photos. I just found the negatives and downloaded them.
Hope you enjoy the photos.
The Flybaby seems to have been converted to a monoplane since I took the
photo.

This link shows it still as a biplane:

Apparently the Texan is in museum now in Texas. The Wild Goose was destroyed
in a crash near Keizer, Oregon. Fuel line disconnected the pilot made a
wheels down water landing.

The Pitts was destroyed and pilot killed at Vancouver, WA 21 August 1977.
The Cessna 120 is apparently alive and well in Alaska. The Bucker
Jungmeister is apparently also still active.
