M1-92, a.k.a. Minkoski's Footprint nebula, is a pre-planetary nebula (pPN) well studied at a wide range of wavelengths (from cm-radio waves to the optical). We have used NOEMA maps and single-dish data from CO isotopologues to model M1-92 with SHAPE and SHAPEMOL in order to obtain more information about the nebula and its evolution.
