Many years back, when M. C. Silvy retired from business, after the "carte mania" was over, he advertised in the daily papers that all his negatives were for sale, and that his late sitters could purchase them if we remember rightly for half-a-guinea each. In this manner a large number were disposed of, many persons purchasing their negatives, not because they had any use for them, but simply to avoid their falling into other hands.
