Designed by Morris F. Benton for ATF in 1915. Similar to his Freehand, drawn a couple of years later, but has plainer caps, lower contrast, and shorter descenders [McGrew 1993]. Sold by Stephenson Blake as Runnymede and offered by Letraset before 1981 under that name.
Queen Empress (2002, used for sample) is an auto-traced digitization by Paul Lloyd, probably based on a showing of Motto in 24 Calligraphic Display Fonts (Dover, 2001).
