A selection of four VLA radio images of gravitational lens systems from the MG, JVAS, and CLASS surveys. The data was obtained during the CLASS observations, and consists of 30-second “snapshots”, thus demonstrating the superb sensitivity of the Very Large Array. CLASS VLA radio images of (non-CLASS and CLASS) gravitational lenses: Upper Left, B0957 + 561; Upper Right, MG0414 + 055; Lower Left, CLASS B1608 + 656; Lower Right, CLASS B1933 + 507.
