  We explore the space of static solutions of the recently discovered
three-dimensional `New Massive Gravity' (NMG), allowing for either sign of the
Einstein-Hilbert term and a cosmological term parametrized by a dimensionless
constant $\lambda$. For $\lambda=-1$ we find black hole solutions asymptotic
(but not isometric) to the unique (anti) de Sitter vacuum, including extremal
black holes that interpolate between this vacuum and (a)dS$_2 \times S^1$. We
also investigate unitarity of linearized NMG in (a)dS vacua. We find unitary
theories for some dS vacua, but (bulk) unitarity in adS implies negative
central charge of the dual CFT, except for $\lambda=3$ where the central charge
vanishes and the bulk gravitons are replaced by `massive photons'. A similar
phenomenon is found in the massless limit of NMG, for which the linearized
equations become equivalent to Maxwell's equations.
