McDougal, Artist, Has returned to his studio, No. 251 Broadway, corner of Murray street, over Tenney’s, in Plumbe’s. Mr. McD. Is enabled by a process peculiar to himself, to copy Daguerreotypes, no matter how dim or faded, and give the expression as well as if from life.
J. A. McDougal is not listed in other photographic directories. This is probably James Alexander McDougall Miniaturist and portrait painter, and not a daguerreotypist.
