What you have looks to be a reproduction of "Beatrice d'Este" by Leonardo Da Vinci. Giovanni Ambrogio de Predis could have created a copy of Da Vinici's work as artists were and still are known to do. From the photos it does not appear to be an oil as there is no crackling like one would expect to see on an oil from that long ago and if it was an oil on canvas it would not be on paper and would not have typing below it. The typing must be information relating to the work that is represented above which means it must have been purchased as a memento from a show of some sort. I am sorry it is not better news and that is just one opinion. I can suggest taking it to an auction house or even an antiquities dealer near you and having them take a look at it for an evaluation in person. Best of luck.
