During the late 1960s and early 1970s I loved trying to catch seagulls in flight. I burned many rolls of tri-X firm trying the get the right shot. My wife often laughed as she looked at my contact sheets with many seagulls with missing body parts. Fortunately I did get a few "whole" seagulls so I was ready when Mr. Seagull's book caught fire.

Note: In those days I bought firm from New York in 100 foot roll and loades by own firm. I also did my own processing so I could shoot a roll of fim and process it for about 25 cents.
