We have constructed a broad-band spectrum for GRB 930131 (the ``SuperbowlBurst''), ranging from 20 keV to 200 MeV, by combining spectral informationfrom the Gamma Ray Observatory's BATSE, COMPTEL and EGRET instruments. Wepresent general methods for combining spectra from different time intervalsobtained by the same instrument as well as for combining spectra from the sametime interval taken by different instruments. The resulting spectrum isremarkably flat (in nu F_nu-space) up to high energies. We find that thespectral shape can be successfully fitted by the shocked synchrotron emissionmodel of Tavani. We present evidence that the flatness of the spectrum at highenergies is not due to spectral time-variability.Comment: ApJ accepted, 10 pages, 1 table, 3 figure
