On an Easter Egg hunt.
I'm trying to locate a copy of ANYTHING related to Doublemont Chevrolet in Louisville, KY circa 1970. I'd love to find an old dealership plate, sticker or even a copy of an ad from these guys from back in the day but no go. I'd like to either find an original sticker (or even a photo of one or a scan of an ad with their logo) and have one reproduced for my 1970 Chevelle. Doublemont is gone apparently.
I've checked eBay, spent a few solid hours on Google's news engine. No papers from the Louisville area have been scanned yet. 
Any ideas or can you think of anywhere I should check for this? 
The search is actually kind of fun. 
Thanks in advance!
