"The first Hand Book gave to the American manufacturer business maps of every state with all political references removed--the number of retail and wholesale merchants in eight leading lines in every town of over 1,000 population showing its location and importance, and the buying radii for the different sized places. On the maps, the buying centers from 1,000 to 2,500 were printed in red, 2,500 to 25,000 in green, and over 25,000 were printed in black."--Page 3
