Its artistic highlights regarding painting are the huge ceiling frescos by the great
Giovani Battista Tiepolo. The present post features the fresco in the Treppenhaus. This link notes:
"... in the great vaulted ceiling over the Treppenhaus - at 7287 square feet (677 square metres) one of the largest expanses ever to have been covered in fresco - the theme was "Allegory of the Planets and Continents." This monumental mythological painting, which occasionally encroaches onto architectural elements below, extends over a flattened basket vault that spans a complex arrangement of flights and landings. It shows the Four Continents beneath a central Heaven presided over by an art-loving Apollo."
It's that encroaching that concerns us today.
Some encroaching items are sculptures that overlap the painting in places, becoming part of it when viewed from below.
Unfortunately, I haven't been able to find the name of the sculptor or names of sculptors who did the work via Google and Bing searches. Perhaps I didn't dig deeply enough. As it was, the items searches turned up became increasingly less relevant, so I decided not to turn searching into a death march.
Below are some photos I took.

Another corner, two more men.

Segment of the Kaisersaal fresco. Note the sculpted dog.
A charming sculpture in the Kaisersaal -- French appearing, and likely related to springtime. I saw the title and sculptor's name is a catalog at the Residenz gift shop, but didn't buy the book. And now I can't find that information on the Internet. If you can, help me out in a comment.
