People 100 years ago didn't generally think "smile!" when a photograph was about to be made. For one thing, they had to be lengthy exposures and you needed to hold still for awhile or you'd blur out (and some of the workers in these shots did).No on in these pics are smiling. It must have been a pretty bad job.
I don't really think that we've improved much... back then the average worker had a sense of pride and commitment with what they did for a living. Nowadays is just about loggin in the required hours and do as little as possible. No wonder why with all the improvements on technologies and such, we still play on those old horns...What really strikes me, apart from the obvious awesomeness of that many people working at making wonderful, beautiful instruments, is how far we've come in terms of health & safety. All those exposed drive belts & wheels, presses with no guards, etc...yikes! Wonder what the industrial accident rates were like back in those days...
I've never seen one older than about 1918 - when the play-at-home craze really hit. But they obviously existed!C-Tenors! Yay!
