The Tate conjecture predicts the existence of a correspondence between these K3 surfaces and certain Kummer surfaces related to these elliptic curves. A geometric construction of this correspondence is given here, using results of D. Morrison on Nikulin involutions.14 pages, LaTeXAlgebraic GeometryNumber Theory14J28; 11G35text
