The chance projection of the disk of Mrk~1456 onto a background QSO issimilar to the case of SBS 1543+593/HS 1543+5921. Mrk~1456 is a luminous,late-type spiral at z ~ 0.05. Though the QSO, SDSS J114719.90+522923.2 at z ~2, has not yet been observed with ultraviolet spectroscopy, it shows strong CaII absorption at the redshift of Mrk 1456 which gives evidence that it is apossible Damped Lyman Alpha absorber. Spectroscopy of the star-forming nucleusof Mrk~1456 allows us to apply emission-line diagnostics to infer the chemicalabundances at the center of the galaxy, and to make a prediction of theexpected metallicity on the sightline to the QSO.Comment: 23 pages, 4 figures, accepted for publication in A
