Marquee '66 Poster (Bob Masse) - authentic?

[siderealxxx]

Hi, is the Bob Masse Marquee '66 poster an original design from March 1966?

I seem to recall reading somewhere that it was a more recent design made to look like it was from the 60s, but can't find that info anywhere now.

It seems to me the design is too advanced/psychedelic-style for an early '66 design, and not consistent with the way the band were named at the time.

Any insights? I like it but really not sure it's an original era design. Thanks!

I don't think so, although Bob Masse seems to have been designing posters since that era, but not in London:

It would've been 'The Pink Floyd' not Pink Floyd at that point...
