You can buy Jack Keroauc's letter to his mother ... for $22,500

Jack Kerouac fans should perhaps say a silent thank-you to his mother.

That is, assuming she heeded his plea for $25 to help him travel from Denver to California.

But given that he signed the letter — now on sale for $22,500 — with several kisses and dotted it with emotional pleas, how could she not have?

The Guardian reports that the 1947 letter from the On The Road author is being sold online through Abebooks by rare-book dealer Whitmore.

Kerouac wrote the note during the peak of the travels that formed the basis of his signature novel, published a decade later.

Whitmore observes that the item is significant not just because of Denver’s later key role in Kerouac’s novel, but also because it dispels the idea that he was aimless: “As he charts his path west, he plans out money and transportation, telling his mother about the need for efficiency if he’s going to meet his goals.”
