If you're a Steve Jobs fan, you can soon own a signed, handwritten letter penned by the late Apple co-founder at age 18. But it won't come cheap.

British auction house Bonhams is set to auction off the letter, which Jobs wrote to his childhood friend Tim Brown, on Nov. 3. The auction house expects the one-page note — which features Jobs' thoughts on Zen Buddhism and his plans to travel to India to attend the Kumbh Mela, a Hindu pilgrimage and religious festival — to fetch between $200,000 and $300,000.
