Brown’s American Ambrotype Gallery, No. 95 (Baldwin’s Block) Superior Street.  The Attention of the Public is respectfully invited to the Gallery, just opened for the production of this new style of Pictures, which is universally admitted to be far superior to any kind of Likeness yet produced by the Photographic Art.

The Ambrotype is taken upon Plate Glass, to which an other plate of glass is hermetically sealed with an indestructible cement; this imparts to the picture a richness of tone which cannot be obtained by any other method, and also renders it imperishable.

The Ambrotype is patented in the United States, Great Britain and France by Mr. Cutting.  I have purchased the sole and exclusive right to make these pictures in Cuyahoga County.  The Public are therefore cautioned against pictures made on a single plate of glass, and falsely called Ambrotypes; and all persons making pictures in this way, and calling them Ambrotypes, are using my trade mark, and thereby rendering themselves liable for damages.

The public are most respectfully invited to call at my rooms, and inspect this new style of likeness.  Pictures from the smallest to the largest size take irrespective of weather.  Children taken in from 2to 6 seconds.  E. W. Brown, Proprietor of the American Ambrotype Gallery, No. 95 Superior St.
