The DW and CW sigs are almost identical handwriting... Brian's is far too legible, even for 1974 and the W on all the Wilson's is way too similar... Alan's might be close... and Mike's (I'm assuming it's his) looks nothing like. My two cents is, they're all fakes. Hope you didn't pay too much.
Didn't buy. Wanted some opinion before I did so. Thanks to very one who replied.
