This "Tracks" guy comes up with some Brian stuff once in awhile:
"A small piece of paper that has been signed by Brian Epstein on one side and Gerry Marsden on the other. Brian has signed in a green pen. The signature is nice and clear with no pen smudging or skip marks. Gerry has signed in a blue pen and you can see this coming through on the other side. The signature was obtained at the Imperial Ballroom Nelson circa 1963. Measures 10.5cm x 7cm (4.25 inches x 2.75 inches). Very good condition."
