This picture of <a href="https://en.wikipedia.org/wiki/Duane_Allman" class="extiw" title="en:Duane Allman">Duane Allman</a> was taken from a Saturday night show at the Fillmore East's final weekend. Unfortunately, this particular scan is a poor one, but will eventually be replaced by a fresh print.
