Annuities of £20,000. black. Similar to previous lot, but signed by the (second) son of Nathan Mayer. Sir Anthony Nathan de Rothschild, 1st Baronet (1810-1876). When his elder brother Lionel (see next lot) became more and more involved in politics, a good portion of the responsibility for running the family's investment house fell on Anthony's shoulders. He invested heavily in Eurepean railroad construction.
