An image of what is believed to be the lensing galaxy of the quasar PG 1115 + 080 was obtained by using an RCA CCD at the CFHT. The photometry of the galaxy is R = 20.20 mag, V - R about 0.70 mag and (B-V) at least 0.75 mag. Comparison of the photometry to synthesized colors of redshifted galaxies suggests that the object may be a spiral with z = 0.3 to 0.45. The redshift range is also in approximate agreement with the predictions of an isothermal lens model as applied to PG 1115 + 080. Photometry of the individual QSO components suggests that all components have the same colors. The flux ratio of component A1 to A2 was about 1.27 on Feb. 19, 1986.
