Query: Abelian Fourfolds of Weil type and certain K3 Double Planes   Double planes branched in 6 lines give a famous example of K3 surfaces. Their
moduli are well understood and related to abelian fourfolds of Weil type. We
compare these two moduli interpretations and in particular divisors on the
moduli spaces. On the K3 side, this is achieved with the help of elliptic
fibrations. We also study the Kuga-Satake correspondence on these special
divisors.
