Below, the Thomas Organ "Million Dollar" fold-out catalogue from late 1964, the "million dollars" in question being the million dollars' worth of equipment that Thomas ordered from Jennings Musical Industries in late August '64 - see this page for more.
This copy was issued to Zeb Billings Music in Milwaukee. Relatively few of these catalogues survive as they were regularly superceded. Details are to be found here. A copy of the catalogue can be seen in a published photo taken before April 1965.
