(above) The earliest fat lady promotional postcard I've seen, published in Germany in the "gruss aus" style circa 1900. Jenny Letto 19 years old, 424.5 pounds.
Olga, the colossal lady, Germany circa 1910
Circa 1905, also in the "gruss aus" style and published for sale at German carnivals/fairs, the location of which would be written or rubber-stamped after "Gruss..." Many of these small town "volkfestes" featured menageries with human anomalies: fat ladies, giants, strongmen, etc. Still fairly easy to find at postcard shows in Germany, especially in comparison with the rare promotional card for Jenny Letto.
The woman of the future replacing man. A German "amazonia" fantasy, popular at the turn-of-the-century. Lithographed circa 1905.
