These 2 brochures came from a Mercury showroom around 1950. One is about the new "Merco-Therm air system for "All-season comfort". It is a fold out brochure. It is 8-1/2" wide x 5-1/2" tall.
The second brochure is about "Merc - O - Matic Drive!" I think this is probably one of the first "automatic transmissions". This brochure or booklet is 14 pages. It is 9-3/8" wide x 7-5/8" tall.
These two brochures are a bit dirty from storage. The second one was folded in half.
