2017 saw the auction industry bounce back after two years of decline. It seemed that each week saw another masterpiece consigned to the auction block and another record broken. However, the auction world is still waiting for its first big sale of 2018.

With iconic motorcycles up for grabs at Bonhams and rare artworks on the block in Arizona, could that change this week?

Here are some of the rare, expensive and unique items up for auction.

Signed Albert Einstein letter

Guide price: £2,500-£3,000

Despite a handwritten note by famed physicist Albert Einstein fetching $1.7m at auction last year, this hand-signed letter has been given a modest estimate of £3,000.

While this letter doesn’t offer the same level of insight as the theory on life note, Chaucer Covers & Auctions will be hoping that the well-preserved signature pushes the prices up at their Autograph Auction sale on Friday, 26 January.

Banksy – Balloon Girl print

Guide price: £15,000-£20,000

After first appearing in 2002, anonymous street artist Banksy brought back his Balloon Girl painting in 2015. Balloon Girl has since appeared in various forms based around major events, such as the Syrian refugee crisis and 2017 UK general election.

This has pushed the price of a Balloon Girl print up. Similar offerings have sold for five figures in recent years. Phillips expects this print, one of 600, to fetch a similar sum at their Evening & Day Editions auction in London on Thursday, 25 January.

Andy Warhol – You’re In

Guide price: $40,000-$50,000

One man’s trash is another man’s treasure. This may look like little more than a Coca-Cola bottle sprayed silver.

However, art collectors will recognise this as a rare piece by famed pop artist Andy Warhol. In total, Warhol made 100 of these signed sculptures.

Given how rarely they appear on the auction block, prices have reached upwards of $120,000 in the past.

Stanford Auctioneers will be hoping for a similar result at their Fine Art, Pop Art, Photographs auction in Arizona on Friday, 26 January.

Brave and Bold #29

Guide price: $100-$50,000

It might not be that highly coveted Action Comics #1, which introduced the comic book world to Superman. However, DC Comics’ crime-fighting super-group, the Justice League, should earn A Ok Auction Company a fair price at their The Estate of Dr. Robert Evans sale on Saturday, 27 January.

Published in 1960, long before they were the stars of the DC Universe, the Justice League had made just one prior appearance before starring in this issue of The Brave and the Bold.
