4 Little Handpainted Tiles...Who, What, Where, When..Don Quixote

I recently inherited from my late Mother these four 3" x 3" tiles which seem to be telling the tale of Don Quixote. Having traveled to Spain during her lifetime, it's possible that she purchased them there but I didn't know about their existence until recently. She or someone has glued felt to the bottom of each tile so I pulled one back to see if there were makers marks, but there aren't any. I will appreciate your information to help me establish their "credentials."
