Hi,
My grandfather and father had a Chrysler Plymouth dealership from 1925 to 1969, and after cleaning out my late dad's storage space, I'm gradually putting some items -- photos, brochures, promotional materials, and other miscellaneous things -- up on eBay in my personal account: jeoffreycat

For simplicity, I'm doing everything with a 7-day auction, because I have no idea how much they are worth.
There's one thing related to the dealership up now but I'll be posting others in the coming few days.
FYI: I'm having a 1932 Plymouth from the dealership restored, so the proceeds will go to that.
Thanks for your interest.
