From a really old philosophy book, the printer's mark for William Pickering. If I remember right, the dolphin and anchor mark originated with the Italian printer Aldus Manutus (Aldo Manzetti), a AD printer of classical texts.
German, Andreas Wechel, came from a family of printers. Wechel fled Paris after the St Bartholomew’s Day Massacre and moved his business to Frankfort. His name is associated with printing work by Bruno and other European Humanists, but an exact copy of Wechel’s printers mark reappears again, not in Germany but in London, on one of the earliest versions of one of Shakespeare’s most famous plays, King Lear.
