Thank you, Fred.
I've been in signs 40 years and did not know Wright designed lettering. His art deco letter styles seem to have been designed in conjunction with specific projects.
Our dentist client told us he designed his own "logo." Apparently he just chose a letterstyle he liked and then topped it with some clipart he found. Now I'm wondering if the image above the lettering is also a Wright design. It looks like it could be. Maybe the dentist always wanted to be an architect.
At any rate, I have been to the library and have started a bio of Wright (Frank Lloyd Wright—A Life, by A L Huxtable). The record of his personal life seems to be as interesting as his innovative architecture.
