I concur.
Bohman & Schwartz were Pasadena-based coachbuilders who were in business from 1932 to 1947 (after which they went their separate ways, but continued in the trade). That said, they didn't always customize new cars, so the Duesenberg J may be slightly earlier. Note that this one has suicide doors at the front and regular doors at the rear, whereas some were the other way around like modern Rolls-Royce Phantoms. While not quite as expensive as a Delahaye Compétition, it would probably still be worth around $1 million today.
