It couldn't be the late forties because of the floodlight pylon. Hibs installed floodlights in 1953. We played Hearts in our first game under the lights. I was there, aged 8. Then Hearts reciprocated when they installed theirs. So this picture is after 1953 at least.Fantastic picture...looks like it is from the late 40's early 50's period. Look at those fans rolling up there most likely to see the Famous Five cast their magic. The beautiful harp crest above the name.
