A period piece is something of or pertaining to a specific era or time.  Anything evoking a knowledge or feeling of an era can be labeled as such.

The aptly named type font Period Piece JNL reflects the hand lettering found on the cover of early 20th century vintage sheet musical entitled “My Baby’s Arms” (from the stage production of “Ziegfeld Follies of 1919”).

Although strongly akin to the coming Art Deco movement in its lettering style, Period Piece JNL still contains a strong influence of the Art Nouveau era of the 1900s through the 1920s.
