I know this is a long shot, but sometimes an answer is found.

Looking for any information about a "Warren Easter Auction Company". I have no idea what part of the country it was located in.

I suspect that it existed in the mid-late 1960's, and possibly into the 1970's.

An initial search on the internet came up with nothing.
Ask me about my junk, knocking Jasper engine, that failed and had to be replaced at only 2,200 miles, and how poorly Jasper handled the claim.
