Landscape paintings early 50s to late 90s

The original sizes of most landscapes are 120 x 100

My dad has painted more than 130 oil paintings and hundreds of ink and pencil drawings that are not online yet.

Almost all the pictures have been painted in one day.

The colors are almost always applied very pasty, as in Van Gogh.

It is always important to see works of art in the original, the effect is different than in a photograph.
