Fans can bid online for the colourful and abstract images of Wayne Rooney, Javier Hernandez, Rio Ferdinand, Nani and Ryan Giggs, which were created by New York-based artist Craig Redman as part of Turkish Airlines' 'Passenger Portraits' campaign. The portraits have been on display at airports around the world and also at Old Trafford, adorning the East Stand window and car park perimeter on Sir Matt Busby Way.
The special editions in the auction have been coloured and signed by the players themselves. Bidding started on Wednesday 2 May and is due to close on Friday 11 May.
Rio Ferdinand said: "I think the campaign is a great idea and the paintings have definitely brightened up Old Trafford! I really like the portrait Craig has created of me and we all had fun colouring our own versions. I hope they raise plenty of money for the Foundation."
Redman commented: "My portraits are always of people I respect or admire, whether they are friends or celebrities, and this project falls right into that category. Being able to draw the world’s best players from Manchester United is an absolute honour, they are an inspiration to millions of people and I’m lucky to be able to celebrate that with my work."
