SIT Vidicon photometry in B and V from the CTIO 4-m telescope is presented for NGC 1466, NGC 2203, NGC 2210, and NGC 2257 in the Large Magellanic Cloud. The deepest data are for NGC 2257, where the main sequence turnoff is reached at V = 22.4, confirming Stryker's (1983) inference from photographic data that the cluster has an age comparable to those of the Galactic globular clusters. NGC 2203 is found to be an intermediate-age cluster with a C-M diagram similar to that of NGC 7789 in the Galaxy. For NGC 1466 and NGC 2210 the present data are compatible with previous studies that have found these to be genuinely old clusters in the Galactic globular cluster sense.
