Alabama Highway Map Cover from 1973

I've done a lot of map posts on this blog, and there's a reason for that--I love maps! Back in March I did a couple of posts on "Some Alabama Highway Map Covers" using mostly official maps from the state highway department in my collection. Those are the free maps you can pick up at state welcome centers and rest stops. 

The oldest one in my collection was an example from 1976. Recently I explored a consignment shop here in Pelham and came across this one from 1973. I thought I'd post it here.

The map has a theme of "Alabama Has It All", something Governor George Wallace explains in his message on the back cover. There's also a quaint template for a stamp and address; I guess the highway and tourist departments would mail them on request and not have to use an envelope.

I wonder when the earliest of these maps was issued. If you know, leave that information in the comments!

This map was modestly priced, but I didn't buy it. Can't collect everything, you know.
