1850                Military Hall, [Jamaica, New York.]

J. L. Armstrong appeared in one announcement in the Long Island Farmer, and Queens County Advertiser (Jamaica, New York) on August 27, 1850.  Daguerreotypes.—Perfect likenesses are always desirable, and an opportunity that seldom occurs, is now offered to our citizens.  The celebrated Daguerrian artist, J. L. Armstrong, has opened his new Daguerrian Gallery at Military Hall, (George C. McKee’s) in this village, where he will remain only a few days.  His pictures are skilfully and artistically made, and his likenesses are finished in such a manner as are warranted not to fade.

J. L. Armstrong is not recorded in other photographic directories.
