Wow!  Hard topic - how to choose!  That is like asking me which of my children is my favorite.  Totally depends on my mood.  My brother and I play a game when we are at museums or galleries - choosing our favorite in each room. 

A favorite day 7/22 our wedding anniversary and I believe the year was ‘91.  The Kimball Museum in Ft. Worth, TX was presenting the Barnes Collection.  My husband and I stayed for hours - I loved "the dance" and another one  of a woman with a colorful shaw.  The poster did not do it justice so I only have my memory to enjoy.

Two Young Girls at the Piano, 1892
Auguste Renoir (French, 1841–1919)
Oil on canvas

I can look at this painting for hours in Musée d’Orsay and not get tired of it. It’s enchanting from any angle. I wouldn’t take it from the museum, however.

MUSEE DES BEAUX ARTS

About suffering they were never wrong,

The Old Masters: how well they understood

Its human position; how it takes place

While someone else is eating or opening a window or just walking

dully along;

How, when the aged are reverently, passionately waiting

For the miraculous birth, there always must be

Children who did not specailly want it to happen, skating

On a pond at the edge of the wood:

they never forgot

That even the dreadful martyrdom must run its course

Anyhow in a corner, some untidy spot

Where the dogs go on with their doggy life and the torturer’s

horse

Scratches its innocent behind a tree.

In Brueghel’s "Icarus*," for instance: how everthing turns away

Quite leisurely from the disaster; the plougman may

Have heard the splash, the forsaken cry,

But for him it was not an important failure; the sun shone

As it had to on the white legs disappearing into the green

Water; and the expensive delicate ship that must have seen

Something amazing; a boy falling out of the sky,

Had somewhere to get to and sailed calmly on. 

Auden
