Ca. late 1950's or early 60's, yellow porcelain bathroom sink and faucet made by American Standard. By the looks of it, this was used as a tile in. It could be used as an undermount, with a hudee rim, or, since it has a finished edge on three sides (not the back) and a little bit of an overhang all the way around, you might be able to use it as a drop in. This one even has a drinking fountain attached to one side. Sink shows some minor wear from use, but not serious damage noted. This faucet may not comply with current EPA lead-free plumbing regulations.  Non-compliant fixtures are illegal to sell for potable water services or where human consumption is anticipated.
