Rare wooden plaque with a lithograph of Savannah, Ga, commemorating their 1876 Centennial. The plaque was made H.J. Toudy and Co., (Phila, Pa), and designed by William Brotherhead. I was able to find only two other plaques like it in an online search. One can be found at the website of the Georgia Historical Society, and the other was sold as a "rare, authentic" plaque on ebay. I was unable to determine how many similar plaques were actually made. It certainly appears to be authentic.
