  We present a numerical estimate of the $\gamma^* \gamma^*$ total cross
section at the designed 500 GeV $e^+e^-$ Linear Collider, based upon the BFKL
Pomeron. We find that the event rate is substantial provided electrons
scattered under small angles can be detected, and a measurement of this cross
section provides an excellent test of the BFKL Pomeron.
