    In this interesting paper the authors deal with the interpolation from Lebesgue spaces \(L^{p}\) and \(L^{q}\) into an Orlicz space \(L^{\varphi}\), where \(1\leq p<q\leq \infty\) and \(\varphi^{-1}(t)=t^{1/p}\rho(t^{1/q-1/p})\) for some concave function \(\rho\), with special attention to the interpolation constant \(C\). This result extends also the classical interpolation theorem of Orlicz.
