This guitar may not quite gently weep, but it could at least make a well-heeled Beatles fan cry with happiness.

The VOX guitar played both by John Lennon and George Harrison is expected to sell for between $200,000 and $300,000 at auction in New York's Hard Rock Cafe on Saturday.

The custom-made instrument is the main lot in the Julien's Auctions sale.

Harrison used it while practicing "I am the Walrus" and Lennon while recording a video session for "Hello, Goodbye." It was given by Lennon to Apple Records electronics engineer Yanni "Magic Alex" Mardas in 1967, Julien's said.

It's a "once-in-a-lifetime opportunity to own one of the rarest pieces of Beatles memorabilia ever to be offered," the auction house said.
