Manufacturing based characters, images, etc.
I've been looking at a lot of the recommended free images, characters, etc. and haven't found a ton of great content for when your audience is 90% manufacturing employees. You lose a lot of credibility when the average demographic is blue collar males 25-50 and you start throwing images of Atsumi in a conference room in your training.
Does anybody have any recs as to where to turn for great characters/pics in a manufacturing world?
