15 line Antique XX Condensed
One of the main categories of wood type styles, as outlined by Rob Roy Kelly, the Antiques are characterized by their unbracketed slab serifs (the serifs intersect the stems at right angles, without any curvature). This ff ligature is from a font containing capitals and lowercase, but no figures and limited punctuation. Typepedia defines a ligature as two or more letters joined together to form one glyph. This particular ligature has a funny little ball terminal (a serif-less ending to a stroke) that reminds me of a smiling worm. I could not find a manufacturer’s imprint.
