  Deep CCD photometry down to V=24.5 is presented for the old Magellanic
Globular cluster NGC 2257. The main result cna be summarized as follows: i) the
RGB Bump has been detected at V=18.7+-0.1, and is compatible with determination
of this feature in GGCs; ii) NGC 2257 seems to be 2-3 Gyrs younger than a
typical GGC; iii) the helium abundance has been estimated to be Y=0.21+-0.03,
using the R- method as calibrated by Buzzoni et al., 1983.
