MASTERS AT WORK! This quarter plate was embossed on the cover of the subjects? complete leather case with this information: ?Williamson Bro. Brooklyn NY?. The oval shaped brass mat had ?C. H. WILLIAMSON BROOKLYN NY? stamped in the lower left corner. Charles and his brother Edward were the finest American colorists in the 1850s! I always rank their dag making capabilities in the top five operators! While these lads weren?t happy about sitting still for their likeness that was recorded on an exquisitely polished silvery mirror, the piece crackles and exhibits the brilliance that the firm routinely achieved. The holographic depth revealed in this portrait simply could not be surpassed! Natural oxidation adds extra colors to the image. The only two brown dots (there are several others elsewhere) that are noticeable are on the older boy?s temple and ear. The other specks and flecks aren?t really seen at all. I am always amazed when I examine the hands of sitters both young and old. Who would have thought that these perfectly dressed and composed lads would already have such gritty fingers? If you don?t have a perfect dag by Williamson in your collection this one would be an excellent addition!
