Here's an ad for Lorain National Bank from that 1968 Greater Lorain Chamber of Commerce promotional booklet. As a graphic designer myself, I find a lot of things about the ad kind of interesting.
First of all there's the bank's logo. Although it is somewhat generic, there is a powerful simplicity about it that seems appropriate, especially since at that time Lorain was quite an industrial powerhouse. (Since then, both Lorain National Bank and its competitor, First Federal Savings of Lorain have both adopted logos (at right) that emphasize the whole "vacation playland by the lake" aspect.
The thing I really like about the ad is the use of illustration. It's a nice little montage by some unsung commercial artist. Custom illustration (and photography as well) is certainly a dying art in this age where you can buy some pretty good stuff online for twelve bucks.
