Garrick Mallery (Wilkes-Barre, Pennsylvania, April 25, 1831 - October 24, 1894) was an American ethnologist specializing in Native American sign language and pictographs.
Selwyn Dewdney was the first scholarly figure to discover the pictographs.
Panamint City is the site of the largest and most elaborate group of Coso Painted Style pictographs.
An early modern example of the extensive use of pictographs may be seen in the map in the London suburban timetables of the London and North Eastern Railway, 1936-1947, designed by George Dow, in which a variety of pictographs was used to indicate facilities available at or near each station.
