The boys (and young men) in the image look to me like newsboys (no doubt, employed by the Vancouver World newspaper) who had gathered for this photo in the morning shortly before or after delivery of the early edition, with their lunch sacks in hand. The gent at left foreground seems to be trying to gather the lads into good photo-formation. I suspect he is the photographer’s assistant. Poor guy, it looks like a case of trying to herd cats! It’s fun to zoom in on the boys at different places. They look like a bunch of characters!
At one time, there was an eating establishment on the ninth floor of the building called the “Nine Maidens” cafeteria, named for the maidens (aka “caryatids“, creations of the great and prolific Vancouver sculptor, Charles Marega) which enhance the exterior appearance of the building. I have no idea if there is a cafeteria today in the building, but I rather doubt it.
