Abstract
We present the preliminary results of an on-going near-IR low resolution spectroscopic follow-up of a complete sample of 30 bright (K'<18.5) EROs selected over 360 arcmin^2 from the MUNICH survey. Among the 13 EROs observed so far, 7 turned out to be early-type galaxies at 1.2<z<1.45 with stellar masses in excess of 2x10^11 M\odot. These 7 early-types account for 40% of the local population of bright ellipticals providing a lower limit to the density of massive early-types at z>1.
