A first solution for the eclipsing binary TYC 4481-358-1 has been found bycombining the results of BVIc-photometry with known stellar models and stellarspectral energy distributions (SEDs). The binary shows total and annulareclipses in a circular 90-days orbit. Masses, radii and effective temperatureshave been derived: about 3.01 Msun, 14.29 Rsun and 4950 K for the giant, andabout 2.39 Msun, 2.39 Rsun and 9600 K for the dwarf. The peculiar dwarf isdiscolored and shows a Teff - passband dependence from 9000 K in the Ic to 9800K in the B band. The giant is in its final stage of core helium burning. Theinterstellar extinction in our line of sight is considerable (Av about 1.44 magat an elevated Rv of 3.58).
