I did read Tarot cards and tell fortunes, but not at carnivals, and not between the two World Wars!
But it was my father who taught me how to read tea-leaves and he always said that he learned it from the gypsies during his carnival days. Now that I am older, I am not sure how many of the stories he told me were true, and how many were tall tales. He was born in the Ozarks and had an entertaining way of relating stories about himself and his brothers, so being a natural storyteller he may have embroidered some.
