Bonhams will tell the Story of the 20th Century through an auction of iconic collectibles on June 4 in New York, with two original rainbow Apple logo signs from the computing firm's original headquarters set to highlight.
The now-iconic logos were removed from the Cupertino, California building and given to a long-time Apple employee in 1997. With the larger of the pair measuring 46 x 49 inches, they will be sold as a single lot for $10,000-15,000.
The rainbow logo was in use between 1977 and 1998, having been designed by graphic artist Rob Janoff, with the coloured strips approved by Jobs himself. It appears on every Apple product of the era, but has now been replaced with an almost identical, yet monochrome logo.
A prototype of Apple's Macintosh LC computer, made from painted foam, is estimated at $1,200-1,800.
Apple has become one of the most iconic companies of the internet age, and its early machines are now realising huge sums at auction. The record for an Apple-1, the first product to leave Steve Jobs' bedroom, was set at $668,000 in 2013.
A diverse range of items traces 20th century history in the auction, ranging from TE Lawrence's personal copy of Seven Pillars of Wisdom ($70,000-80,000) to photographs of aviation pioneer Samuel F Cody ($150,000-200,000).
