  We report the detection of a very red source coincident with the
gravitational lens 1938+66.6 (Patnaik et al. 1992) in K' (2.12 micron), H (1.6
micron), J (1.25 micron), and Thuan-Gunn r (0.65 micron) bands. 1938+66.6 has
previously been detected as a partial radio ring indicating lensing. We find
K'=17.1 +- 0.1 and r = 23.9 +- 0.2, making it a very red source with (r-K')=6.8
+- 0.25. We also observed in Thuan-Gunn g band (0.49 micron) and found g>24.5
at the 90% confidence level. We interpret our observations as a reddened
gravitational lens on the basis of its optical-IR color and positional
coincidence with the radio source.
