I have a soft spot for unicase fonts and recently discovered that ITC Franklin from the Font Bureau has unicase alternates. It’s not clear when they were added to the range, but I’d guess that David Berlow added them in 2008. With so many ITC Franklin fonts out there, be sure the one you get has the unicase alternates.
