Signed and numbered "120" in white ink on verso of the image by Antoin Sevruguin in cyrilic. The image, however, is located on a card enscribed by Dmitri Ivanovich Ermakov. This suggests that this photograph is an example of colloboration by Ermakov, who would buy photographs and negatives from other photographers and sell them himself. An example of this was work produced by Alexander Roinashvili, who died in 1898. This photographer's archive was subsequently acquired by Ermakov.
