In September 1909, the Edison Phonograph Monthly contained the following article noting the placement of an immense billboard to locate the birthplace of the phonograph.

Locating Menlo Park

Not one passenger in a thousand traveling on the Pennsylvania railroad between New York and Philadelphia, knows where Menlo Park is located, although nearly everyone knows that the little town was made famous because Thomas A. Edison for ten years had his laboratory there. The “Wizard of Menlo Park” was the title given Mr. Edison because of the many important inventions born in the Menlo Park laboratory.

We have put Menlo Park on the map by erecting directly opposite the station an immense bulletin board, bearing the words “Menlo Park – Birthplace of the Edison Phonograph.” The sign is reproduced in the above illustration. It is 20 feet high and 125 feet long, one of the largest of its kind in the country.

Its size and location can hardly fail to inform every passenger on the Pennsylvania railroad just where Menlo Park is located.
