I am not sure what was the original intention of this early 20th Century postcard.
It follows the theme of the anti-suffrage propaganda, that is, if women got the right to vote, it would lead to a gender role reversal.
But the postcard makes no reference to the suffrage movement. So is it anti-marriage propaganda or simply a joke about the state of harried married males?
In any case, the male’s femulation is disappointing.
P.S. The woman in the before and after scenarios looks like the same woman, but the male looks different. In addition to wearing a dress, he looks shorter and has a mustache in the "after" scene.
