  An elliptic two-parameter deformation of the (universal enveloping
superalgebra of) affine Lie superalgebra $osp(1|2)^{(1)}$ is proposed in terms
of free boson realization. This deformed superalgebra is shown to fit in the
framework of infinite Hopf family of superalgebras, a generalization of the
infinite Hopf family of algebras proposed earlier by the authors. The
trigonometric and rational degenerations are briefly discussed.
