From Amnon Shoenfeld:

Contact prints of Bob and friends, circa 1977.
EdO: Right column, second from top.
Bruce  Applebaum, friend fron the 60s onward:  middle
Patty Forman, friend from the 60s onward: Right column, top.

EdO remarks: I remember, with luck correctly, that this was
a party (in Seattle) at Bob's friends Ed and Patty Forman's
house. Bob Schommer took a lot of pictures at this party,
as did others.  Bob presented EdO with some pictures
from his camera, which unfortunately are lost. Perhaps
Amnon and others can add comments about this
party. EdO originally wanted to blame it on Bob's
graduation, but EdO believes that Bob graduated on
almost exactly his 30th birthday; Bob would be about
31 here. EdO also thinks  that he remembers that Bob
shaved off his goatee  for the night of the graqduation
party. Wonder if pictures of the graduation party can be found.
