Members of the Brighton Swimming Club (a.k.a. "The Brighton Bulge"*) pose for a photograph in their tophats, ca. 1863. Please note time-travelling Stephen Colbert, situated dead center, delivering his trademark smirk of incredulity. Hi-res here.
* Not really, but the moniker fits. The sheer volume of swollen swimwear in this photograph borders on David Bowie levels of ridiculousness.
