Size of the photorealists also. That is what is so impressive about the Chuck
Close work, the size, detail and variations on a theme.
We always like to ask the students to find the "Canneletto's" small
Renaissance perspective landscapes. They are always in rooms near large
Baroque and/or other massive works from the Pre/Post Renaissance. They are
exquisite and would be missed unless you challenge your students to find them.
They are quite amazing, it must have been a "one haired" brush.
