Sales declined steadily for the remainder of the decade, so fewer examples of these later editions exist than the 1936s. The London office of Parker Brothers closed in late 1936 so London was dropped from the box and Chicago was added. This probably happened in late ‘36, but "Chicago" boxes are considered ‘37 or later. Also "A Parker Trading Game" was added (except for the #8) in late ’36, but anything with this slogan and "Chicago" is considered ’37 or later. Many examples of APTG London sets exist. These would be late 1936 sets and are a prime example of the fact that Parker Brothers did not make changes on any set timeline (these sets were probably put out during Christmas rush 1936 as there seems to be an abundance of them).
The sets available in these years included #6 (black or blue), #8, #850 Library edition (sorry, no picture), #9, #10 (now the $5 edition), #12 Gold edition, and #25 De Luxe edition.
"Pencil Sketch" cards make a comeback and are prevalent in the 1937 6,8, and 9 sets (this is probably due to declining sales and Parker Brothers using up old stock). The rules in the ‘37 sets also have 1937 written at the top.
