If I stand in front of a mirror, the light takes a finite, albeit small, amount of time to reach my eye.

So I am seeing myself as I looked some small fraction of time in the past.

Now if I stand with a second mirror behind me, I can see an infinite number of images of myself, each slightly older.

If I had my arm raised, and then I lowered it, can I still see an image of myself with raised arm?

I agree with tht previous comment about the distance, alingment, efficiency of the mirror, etc. , etc.  Also consider this:

If the mirrios were perfectly flat and perfectly aligned, the first reflection would stop you from seeing all subsequent reflections.  Therfore you MUST have a slight misalignment (angular) bewtween the mirrors for the requisit number of reflections to occur.  Assiming the mirrios to be very wide, you could get a large number of alternating replfections, but you could not see those images as the light would never return to your eye. 

So I agree, the answer is no for a number of reasons.
