The State Fair.— The annual fair of the Louisiana Agricultural and Mechanics Association, commenced on Monday last….Daguerreotypes of rarest finish and beauty were exhibited by Messieurs P. Langlume, and J. Maguire, of New Orleans.  These were so well executed, that, to save our lives, we could not tell which excelled, and therefore have come to the conclusion, that they cannot be surpassed….

Extract from the report of the Committee on “Mechanical Inventions and Improvements,” of the “Agricultural and Mechanics Association of Louisiana,” at their last meeting…

Daguerreotypes of distinguished characters, (Heny Clay and Gen. La Vega, among others) were presented by Mr. J. Maguire, of New Orleans.  Others were offered by W. Hutchins, of N. O., and P. Langlume, of Baton Rouge, which had considerable merit, but Mr. Maguire’s were decidedly the most faithful and the most beautifully finished.  If the opinion of the Committee on Fine Arts was the same as ours, Maguire got the first premium.
