D BrownThe Curt Teich company produced postcards from the 1900s through the 1970s -- with pretty consistent typography from the 1920s through the 1960s. Amazingly, their archives still exist and are public, as part of a county collection in Illinois. Here: http://www.lcfpd.org/teich_archives/
There's an email & phone for postcard research inquiries.
Teich postcards were produced in great quantities and most have a number on them that makes them easily dateable -- but this one does not. (It looks like a re-print of someone else's postcard, rather than a Teich original.) There's a handy Curt Teich dating guide here, useful for cards that do have their numbers: http://www.lcfpd.org/docs/teich_guide_dating.pdf
