It's been stretched, squooshed and badly redrawn, but does anyone know what typeface this signage was derived from? My first guess was Albertus, but it lacks a wedge atop the A, for instance.

Holland Title looks promising, although I can't find a decent sample of it online.

And that S looks straight out of an uncial.
I think Marc hit it when he said uncial. Look at Neue Hammer Uncial's caps. (BTW, some books show this as American Uncial (Mecanorma), but Myfonts selections with that name are true uncials, without these caps.)

Dueling font ID's. Not so fast. I still think that Yves was right about Celtic Bold. Here is American Uncial Bold (ICG) -- one Grant should recognize -- credited to Oldstyle in the Image Club catalog from my old Letterpress Collection. It came in 6 weights including open and Initials, with regular and bold weights of each.
