We propose a classical, i.e., local-real physical model of processes underlying EPR experiments. The model leads
to the prediction, that the visibility of the output signal will exhibit increasing variation as the coincidence window is
increased, thus providing a testable criteria for its validity. If it can be sustained, this model undermines the claim that
Nature has a fundamentally nonlocal feature or that irreal entities are required by quantum theory.
