I think a lot of them tended to specialize also. Some clowns were performers who had other circus skills, so could use those. But, they may have become clowns because they could no longer do aerial or acrobatic acts. Still, you had pretty clowns who excelled at makeup and costuming, for example, that weren't always the most humorous. But they could take a great photo. Others were good in a ring, but wouldn't have survived up close, surly as they were. Some were outstanding show clowns, but had sloppy makeup. You never noticed, as you were not up close and their images were not used in advertising. Today, one might ask if the magician with a great street set could hold an audience of kids at a party. Or if the outstanding balloon artist has the temperament to.assist at a hospital sans latex. Does circus clowning translate into up close work? Does the esoteric, artistic puppeteer know how to interact with kids? And how are different kinds of clowns relevant in our time and place?
