While travelling in the States I happened upon a collection of National Geographic magazines from the 1940's. They're chock full of interesting articles and beautiful colour photography - but the Advertisements! They are something else my friend. I love the Strapline for the one above: "The seeds of godlike power are in us still"; (click on the above pic to enlarge).
In the coming days and weeks I'll be uploading more scans from said magazines. They're a hoot!
