Only 40 bottles of Macallan 1926 whisky were produced in 1986. Of those, 12 featured a label designed by Sir Peter Blake, one of the artists who created the cover art for The Beatles' 1967 album Sgt. Pepper's Lonely Hearts Club Band, per Vox. The ultra-rare bottle could now be yours, though "it's probably not one to drink with a cheap cola," per Edinburgh Live. Described as "inconceivably smooth," the whisky, held by a UK collector since its release, is expected to fetch up to $923,000 when it hits the auction block in Scotland on March 6. To become the most expensive whisky sold at auction—overthrowing a bottle of Macallan 1926 designed by Italian artist Valerio Adami—it'll need to top $1.1 million. (Keep an eye out for fakes.)
