We present HST/WFPC2 broadband and ground-based Halpha images, H I 21-cmemission maps, and low-resolution optical spectra of the nearby galaxy ESO1327-2041, which is located 38 arcsec (14 kpc in projection) west of the quasarPKS 1327-206. Our HST images reveal that ESO 1327-2041 has a complex opticalmorphology, including an extended spiral arm that was previously classified asa polar ring. Our optical spectra show Halpha emission from several H IIregions in this arm located ~5 arcsec from the quasar position (~2 kpc inprojection) and our ground-based Halpha images reveal the presence of severaladditional H II regions in an inclined disk near the galaxy's center.Absorption associated with ESO 1327-2041 is found in H I 21-cm, optical, andnear-UV spectra of PKS 1327-206. We find two absorption components at cz = 5255and 5510 km/s in the H I 21-cm absorption spectrum, which match the velocitiesof previously discovered metal-line components. We attribute the 5510 km/sabsorber to disk gas in the extended spiral arm and the 5255 km/s absorber tohigh-velocity gas that has been tidally stripped from the disk of ESO1327-2041. The complexity of the galaxy/absorber relationships for these verynearby H I 21-cm absorbers suggests that the standard view of high redshiftdamped Lyman-alpha absorbers is oversimplified in many cases.
