The images are from the museum's catalogue, a scan of which they kindly provided.
The first is Corner of Farmyard (Hoekje van Boerenerf), c.1897/99, black chalk, 31x41.5 cm.
The second is Row of trees along the Gein (Rij bomen langs het Gein), c.1906/07, chalk and watercolour, 59x84 cm.I cannot find either image in the Catalogue Raisonne, although there are several paintings similar in subject, though not in size, to the watercolour.
[Correction, 23rd Feb, the first is A74 Farmyard in the Achterhoek, 1897-99, shown in the Catalogue as 'Private collection, Weesp'.]
And, of course, Yvonne Louis might have a new Mondrian too.
