In the open cluster NGC 752, 89 stars are observed in the Vilnius seven-color photometric system, including probable members fainter than observed hitherto. Spectral classification of observed stars are made and individual reddening values are determined. The mean reddening of the cluster stars is equivalent E(B - V) = 0.025 m. By fitting on color index-magnitude diagrams the cluster Main Sequence with the Hyades one the distance modulus (m - M)0 = 8.15 +/- 0.15 m is found. For 11 red giant members of the cluster absolute magnitudes are derived and compared with ones of the standard calibration. It is obtained that the cluster giants are on average 0.6 m fainter than giants of the corresponding spectral class in the solar vicinity.
