  Let V be a finite-dimensional superspace and G a simple (or a ``close'' to
simple) matrix Lie superalgebra, i.e., a Lie subsuperalgebra in GL(V). Under
the classical invariant theory for G we mean the description of G-invariant
elements of the tensor algebra of V.
  We give such description for GL(V), SL(V) and OSP(V) and their ``odd''
analogs: Q(V), SQ(V); Pe(V) and SPe(V).
