The lamp is the symbol of light and clearness of vision. Used in its figurative sense it is as old as civilization, for the ancients held the sign of a lamp to mean the power of imagination, illuminating the future.

The symbol of the owl and the lamp combined means Light leading Wisdom.

This is the advertising symbol of the J. Walter Thompson Company. For many years it has been the trade-mark of good advertising.

A clean and bright little fellow who adorns Swift & Company's advertising.

In the case of the unauthorized use of a well-known, extensively advertised catch-phrase, this intention is virtually obvious. For example, if any soap manufacturer should begin to print the N. K. Fairbank Company's celebrated question, "Have You a little Fairy in your Home?" in his advertisements and signs, the courts would doubtless enjoin him summarily, without inquiry into his intentions. This phrase has been used so long by the N. K. Fairbank Co., and so much money has been expended in giving it publicity, that its owners have acquired a valuable property right in it.
