This portrait of Eddy was taken by W. Shaw Warren, likely in 1884, in his Boston-based studio. It was produced as a cabinet card, a thin photograph mounted on a slightly larger piece of cardstock, measuring 4.25 by 6.5 inches This type of photo was intended for sharing with friends and family and was very popular in the 1880s. Eddy sent copies of her cabinet card to a number of her students in late 1884 and early 1885. Unfortunately, it seems the negative for this photo was broken in 1885 and so no more copies could be sent.
