There's one Baldessari work I genuinely love and would like to own, maybe because of my Midwestern roots and love of driving alone. 'The backs of all the trucks passed while driving from Los Angeles to Santa Barbara, California, Sunday, 20 January 1963' consists of a grid of 32 small color photographs depicting just what the title says.

It took the Metropolitan Museum of Art nearly 50 years to wake up to Pablo Picasso. It didn't own one of his paintings until 1946, when Gertrude Stein bequeathed that indomitable quasi-Cubistic picture of herself - a portrait of the writer as a sumo Buddha - to the Met, principally because she disliked the Museum of Modern Art.

Can space break? I mean the space of art galleries. Over the past 100 years, art galleries have gone from looking like Beaux Arts salons to simple storefronts to industrial lofts to the gleaming giant white cubes of Chelsea with their shiny concrete floors.

The last time money left the art world, intrepid types maxed out their credit cards and opened galleries, and a few of them have become the best in the world.

I love Rauschenberg. I love that he created a turning point in visual history, that he redefined the idea of beauty, that he combined painting, sculpture, photography, and everyday life with such gall, and that he was interested in, as he put it, 'the ability to conceive failure as progress.'

The greatest work of art about New York? The question seems nebulous. The city's magic and majesty are distilled in the photographs of Alfred Stieglitz and Paul Strand.

Imagine it's 1981. You're an artist, in love with art, smitten with art history. You're also a woman, with almost no mentors to look to; art history just isn't that into you. Any woman approaching art history in the early eighties was attempting to enter an almost foreign country, a restricted and exclusionary domain that spoke a private language.
