Any ideas what to do with them?  I considered Ebay but there are dozens and dozens and dozens of listings for sale and of the ones I looked at none had a bid and only one had a "watch."  I have a very large bag of maps dating back to the fifties--prior to the interstate highway system being built--that I have transferred from one car to a newly purchased one for all those years and it's time for them to go.  I can dump them into the recycle bin if there is no interest in them by anyone.  I may pull out a few of the earliest ones just to show that there was no interstate system except for a few highways under construction.  On the maps they are shown as =============.
