The First Wonder Woman PSA

This is probably the very first WONDER WOMAN PSA, contemporary with WONDER WOMAN # 3. This one page strip is in support of the March of Dimes, the popular anti-polio charity supported by President Roosevelt (and named by Eddie Cantor as a parody of the March of Time). The "autographed" picture of WW looks a lot like those back cover portraits that Timely had (and that we ran awhile back).
