approximately 48 covers sent after the reorganization of the Chicago Post Office effective July 1, 1894, when all stations were designated by letters, stations represented include A, B, D, E, G, J, K, L, M, N, O, P, S, V, and X, as well as several numbered substation cover including 35, 48, and 56 (which were all carrier substations) and a unique two-line violet "Substation No. 8, Chicago, Ill." handstamp, generally fine to very fine, an impressive group, stations began reverting to their local names in 1899 making this group a fascinating case study of a short-lived experiment in standardization by the post office, see discussion in Piszkiewicz (pages 296-99)
