There are 20 similar images waiting for you to ponder over if you enter the competition, which is being organised to raise money for the Open University Student Association (OUSA) charity, OUSET.
Photographer Joy Clark volunteered her services and photographs for free in aid of OUSA’s student charity, and has done a grand job finding suitable subjects to fool you.
You can pit your wits against Joy for an entry fee of £1 for the chance to win a £25 voucher towards OUSA merchandise or a £25 Amazon voucher.
Pay your £1 entry fee via OUSA’s PayPal link by going to www.ousa.org.uk where you will find the donate button at the bottom of the homepage. Then send your name to firstname.lastname@example.org and Sandra will send you a link to the other photographs, together with further entry details.
All entries should be received by 12 March 2012, all profits go directly to OUSET, the student charity and the winner will be announced in the next issue of OU Student and on Platform.
