So. This font has no actual thimble relevance, except that the name of the font is derived from the Thimble Theatre comic strip-- whence came Popeye the Sailor, et al.--which name I assume somehow derives from the tiny size of the thimble. But I dunno.
Anyway, I like the graphic for the font, at left, which is zippy and fun. Happy Thimble!
The font was designed by Nick Curtis, and is available from myfonts for $20.00.
