For decades, NGC 188 has been the canonical nearby old open cluster, of key importance to studies of the evolution of the Galaxy. We continue systematic study of this fundamental WOCS cluster by expanding the previous WIYN deep study of a small central field, and the previous WOCS KPNO 0.9-meter central 23' field, to a 40' field (2x2 montage of 23' fields) of KPNO 0.9-meter data. The cluster reddening, distance, and age, are discussed. This data will be used in subsequent wide-field WIYN/Hydra spectroscopic studies.
