Printed postcard format depicting the sideshow performer known as Sealo the Seal Boy, shown in full length studio portrait with the printed caption Sealo and The Seal Boy identifying the subject. Sealo was a well-known American sideshow performer with phocomelia, a condition resulting in shortened limbs, who performed under the Seal Boy billing at Coney Island and on the carnival circuit for several decades during the mid-twentieth century.


Sideshow performer promotional postcards such as this example were distributed at performances and collected as novelty souvenirs by fairground and carnival audiences. Sealo cards are among the more recognizable examples of mid-twentieth century American sideshow ephemera and are actively collected within that specialized field. The straightforward full length studio portrait format is typical of sideshow performer card production of the period.


The front bears the printed text: Printed caption reading Sealo and The Seal Boy. The reverse reads: Standard divided reverse. Handwritten inscriptions read: Pencil catalog notation visible.
