  We provide Vasiliev's four-dimensional bosonic higher-spin gravities with six
families of exact solutions admitting two commuting Killing vectors. Each
family contains a subset of generalized Petrov Type-D solutions in which one of
the two so(2) symmetries enhances to either so(3) or so(2,1). In particular,
the spherically symmetric solutions are static and we expect one of them to be
gauge-equivalent to the extremal Didenko-Vasiliev solution given in
arXiv:0906.3898. The solutions activate all spins and can be characterized
either via generalized electric and magnetic charges defined asymptotically in
weak-field regions or via the values of fully higher-spin gauge-invariant
observables given by on-shell closed zero-forms. The solutions are obtained by
combining the gauge-function method with separation of variables in twistor
space via expansion of the Weyl zero-form in Di-Rac supersingleton projectors
times deformation parameters in a fashion that is suggestive of a generalized
electromagnetic duality.
