Lothrop G. Bean was recorded in one advertisement that appeared on December 10, 1857 in the  Lowell Daily Citizen and News (Lowell, Massachusetts).  Great Attraction At Bean’s Patent Ambrotype Hall, 234 Merrimack Street.  His Patent Ambrotypes are all the rage, as they are taken and finished in superior style, and are sealed between two plates of fine polished plate glass, so that they are secured from air and dampness.  Warranted not to corrode or change in any climate.  His pictures can be colored like the Daguerreotype, but are much more beautiful in finish, more soft and delicate in effect, and come nearer to nature than any other picture.

The public are respectfully invited to call and see the difference, between the genuine and the so called Ambrotype, advertised by others.  The genuine being durable, the other perishable.  Jy23.

Lothrop G. Bean is recorded in other photographic directories as being active in Lowell from 1858 to 1859.  Lothrop G. Bean is possibly the same person as L. G. Bean who was active in Westerly, Rhode Island 1853 and in Fall River, Massachusetts in 1856.
