Vintage work crew photos

around 150 would be about the minimum I would want I've tried printing email pictures without first trying to enhance them they are usually around 75 DPI
A trick I have used several times is to up size in Microsoft office to 30% larger at a time then save then auto correct and repeat several times until the saved size is 400% larger than original then print them off on my smaller printer on photo paper they come out more or less fair there is only so much enlargement that can be done but a good scanner can do wonders to a wallet size photo if you want a 4x6 print No where near what a true photo enlarger can do at the lab though and even those depend on the exposure setting the photo was taken on and the clarity and lighting.
