Alpine landscape oil on cardboard 19thsec ( on the back watercolor villa with Italian garden )

Anonymous painting of fine painterly quality with alpine mountain arc in the background in the foreground grazing cattle and interspersing the depth of the landscape is a village (unidentified). Mounted on the back is a watercolor on a stand-alone paper support, the subject of which appears to be a Tuscan villa with a beautiful Italian garden; probably the 2 works are not by the same painter and therefore wanting to be separable. 19th-century frame, external measurements 37x29cm
