someone had a photo of that same lettering on their site.
Was it Corey?

Anyway, I think it's just a fancy lettering job.
If it was anywhere, it would be in a PhotoLettering
or Sign Painter's catalog.

It appears to be based upon some Alf Becker lettering,
judging from Letterhead Fonts' Becker Poster Script.

Another version is The Fontry's ARB-85 Poster Script -
and it's free! (there are two other Alf Becker digitizations
offered for free from here as well).

Edit: Hey, the ARB-85 Poster Script that The Fontry offers
for free download directly from its own website (see the
links just above the 2nd graphic) differs from the one
above and is, in fact, precisely the same as the lettering
on the sign.

Hmm ... no ID credit for finding this font, Yves?

Methinks the font in my Edit above matches the
posted image exactly. I nail so few (he whined)!

So, just to cheer you up, this ID was pretty impressing, Mike..

Hah! Thanks David.
