'A Thousand Kisses,' Signed by the Artist

Typed fan letters like that are no trouble to read. But other letters shown are far more problematic. Their intimacy burns. "I'm using the paint off your palette," Joan Mitchell writes her lover, the painter Michael Goldberg, in 1951. "I'm drinking the beer you left on the windowsill -- & I'm kissing you -- this I do all the time."

Do you think you should be reading this? Gentlemen and gentlewomen aren't supposed to read other people's mail.

In the handsome little volume that accompanies her show, scholar Liza Kirwin, the Archives of American Art's curator of manuscripts, attacks this hesitance head-on.

"Love letters," she writes, "bring out the voyeur in most of us. These deeply personal communications have the power to make us blush."

And perhaps to make us mourn. What gives this show its ache is that the letter age is over. Not entirely, of course, a few well-brought-up people still compose with fountain pens, but pretty much it's gone. The love letter went with it. The telephone helped kill it, e-mail contributed, texting gave the coup de grace, and now the deed is done.

Those in love might nowadays key "luv ya" on their cellphones, but OMG who now has time to sit in fervent solitude intent on the beloved while inking letters one by one? Or the time to find a mailbox (where have they all gone?), the time for free imagining (the mail train, the steamship, the sense of distance crossed), or the time to burn expectantly awaiting a reply?

I'm gonna sit right down and write myself a letter, and make believe it came from you. Fats Waller used to sing that. Bing Crosby, Frank Sinatra, Bill Haley sang it, too . Lotta kisses on the bottom, I'll be glad I got 'em. Now it sounds like an antique. These letters have aged as surely. Once pinioned to the present, they're now artifacts of the past.

Most people hardly know the Archives of American Art, but it serves as a huge resource for American art historians. Founded in Detroit in 1954 (by the historian E.P. Richardson and Michigan's Lawrence A. Fleischman, a dealer and collector), the archives at first collected little more than microfilm of archives from other institutions. It's grown a lot since then. Today its storerooms hold more than 16 million items, 2,000 oral histories and 5,000 collections. It merged with the Smithsonian 38 years ago.

The archives is still growing. It recently acquired, to cite just one example, all the business records of the Leo Castelli Gallery, 400 linear feet of files that show in fine-grained detail how that most ducal of art dealers (Jasper Johns, Roy Lichtenstein, Robert Rauschenberg and Frank Stella were all Castelli artists) did his subtle work.

Kirwin, at the archives, pulls a piece of paper from one Castelli file. It's a carbon of a letter from 1961. A customer, one gathers, had bought a work of art only to discover that he didn't really like it and had returned it to the gallery, asking, with apologies, for all his money back.

Did the dealer tell him to shove off? No, indeed, he did not. Castelli's letter, in its own way, is also about failed love. This is what he wrote:

"Please don't be troubled by your change of heart. High enthusiasm for paintings is a commendable condition, and premature commitment frequent. Fine art is expensive but the desire to own it is not. The gallery is not injured by your decision, but flattered by your spirited attentions."

That's how to sell art.

This is how Liza Kirwin, with comparable understanding, has sold us on her love letters. Too clever to install them in terms of bland chronology, they have been arranged instead, she says, "in terms of fervor, their intensity of passion."

Some time in 1914, the modernist John Storrs (1885-1956) wrote this panting poem to Marguerite Deville Chabrol, the woman he would marry.

My soul hangs upon your
love -- my lips burn to
touch your neck -- your
eye -- your finger tips --
to kiss each breast . . .

From there it just gets hotter. Storrs's letter is the climax of "A Thousand Kisses." Heartfelt is the power of this mild little show.
