Has anybody ever seen these?

Has anybody ever seen these? They are Photos from Oldsmobile showing the new models coming out. They were sent to my stepfathers grandfather in 1938.

there was one of those selling on ebay a few days ago. he had a "buy it now" for $2,500. looked solid and he said it had a rebuilt motor w/ less than 1000 miles on it.

 

Sorry to bump a vintage thread! Any idea of value? They were in the original envelope from Oldsmobile. They were stolen along with some other stuff last week. I’m going to be fighting insurance I’m sure.
Merry Christmas everyone.
