Yes, not long ago there was a picture published (S&T?) that was a B&W image
from several decades ago, superimposed on a negative taken recently. If
there had not been expansion, the light and dark areas would have countered
each other (as they did with the background stars). But each of the
filaments etc showed outward movement.

having seen the picture of the day today at

I wondered is there is any discernible expansion
showing between the oldest photos taken
and ones taken now?
