I'm looking for images from Cadillac sales brochures or magazine ads -- these two models ONLY: 1941 Cadillac series 62 sedanette/fastback -- front 3/4, rear 3/4, or side view (if there was a 61 Sedanette in '41, that would an acceptable alternative). 1940 LaSalle series 52 coupe or convert -- front 3/4 or side view (other series 52 body styles would be OK too. The 52 is the larger of the two '40 LaSalle body series). I don't need photos, unless they're actual GM publicity stills. I'm looking specifically for advertising art. Hard copy would be fine, but digital is OK too. TIA!
