(available at myfonts.com and fonts.com as RoundupCaps)
I like doing typefaces in the spirit of the 19th century. Perhaps this inclination indicates that I am out of touch with the 20th century. If I am, that may not be altogether bad. Though fonts of this sort are often associated with the "Old West" in the United States, they were in common use in the 19th century.
SpicandSpan is a caps-only font inspired by the blocky "Old-West" fonts, which have oversized serifs, but in this one the serifs are not blocky but are round. RoundUp is a further development of this face.
