Hi Gordo,
I honestly have no axe to grind, but having met the seller, yes, I do still believe he is genuine. I bought two lovely lettering-only signs from him, and within the last couple of months he has also sold a good, rare Smith's smoking mixture, and a very nice Adkins packet pictorial too. He also has a couple of genuine signs on at the moment; a Colman's Starch, and a Nectar Tea. I know the Robin is a repro, (and was surprised he didn't recognise it as such,) but am uncertain about the Player's mirror. I'm not sure that this counts as 'a lot of repro signs' though! Maybe I missed other repros he sold?
