The House first printed passes for the visitors’ gallery in 1877, when Congress met to count the electoral votes in the disputed 1876 presidential election. The House and Senate met in Joint Sessions 15 times in February 1877, issuing color-coded gallery passes each day, until—acting on the decision of the bipartisan commission created to resolve the election—it awarded the disputed votes to Rutherford B. Hayes, granting him the victory over Samuel J. Tilden by one electoral vote.
