Imagination in business by Lorin F. Deland

It's a quick read. Only around 50 pages. Worth reading for some great business gems which are still relevant today (eg always tell people why the price as well what it is). It's also a fascinating insight into the early 20th century - eg the casestudies used make it clear that the motor car is not yet a part of everyday society.
