Although this doesn't exactly pertain to the trading pit, I couldn't help but post this early 20th century booklet on "The Scalper: Who he is, what he does and how he does it" mainly cause I thought the drawing was great. It was put out by a brokerage to help off floor traders learn about how to scalp and basically get customers to trade through that brokerage. One thing that hasn't changed in the 150+ years in the futures industry is all the scumbag brokers looking for new and ignorant clients to rip off. At least the early versions of marketing spam such as this were a bit more original than modern day shills put out.
