Typeface inspired by the ‘Viewing theatre’ signage and in turn Commercial Classics Caslon Italian (their revamp of Caslon's Display type from 1821).
Having always (incorrectly*) associated it with the American Frontier or “Wild West” or “Circus” types, I'm always excited when I see it elsewhere and away from those contexts. Such a playful typeface with all the inverted strokes and weights I particularly liked this italicised version.
* I say incorrectly as I mistook them for the French Antique which was developed off this typeface and to quote Wood Type Research's blog, "gained enormous commercial popularity as it spread quickly to continental Europe and America. It became the dominant display style of the mid-1860’s until the end of the 1880’s, with an expansive range of stylistic variation."
Other (non italic) versions out in the wild.
