Published 1930 by Compass Sales Corporation. From a review by Alfred Armstrong in 2006: ?Sales people are notoriously always looking for a way to get an advantage - over their customers, their competitors, and their coworkers alike. The most able seller can almost read the minds of prospects and understand their hidden motivations, their needs, their fears, but most are not so gifted. Hence the continuing market for works which purport to teach skills. Judging by the content of the sewing compass, a quaint little ring down set of guidelines for sales people in 1929 the hot gimmick was physiognomy for face reading. Does your customer have a protruding forehead and chin? Then he?s a deliberate thinking controlled acting buyer and must be treated accordingly. Maybe though he has a head which bulges over the ears. Then he?s a dynamic buyer who wants action even when being entertained.? This particular wood constructed box set was made for a Dr C.W. Holz printed on front of case. The two volumes are in excellent condition and don't appear to have been used. There is no writing on any of the pages. The case shows some age and wear as pictured. Appears to have a 1930 date with initial printing in 1929. Loose pages (probably additions) are nestled in the back of one of the two leather bound books. Inside it appears one of the wood separators is missing. This is a one of a kind collectible for the ultimate salesperson or collector of antique sales kits. Will ship USPS Priority with tracking to winning buyer. Will require a signed delivery receipt to protect both buyer and seller. Seller will pay for all shipping costs.
