The competition was devised as part of a new museum marketing strategy funded by the East Midlands museums Hub, which is part of Renaissance, the national museums development scheme to promote the work of regional museums. Each entrant simply had to fill out a postcard available in local museums free-of-charge.
Emma, 40, added: "I just saw the postcards on a stand and decided to enter on a whim, I didn't expect to win at all."
She originally took her children Jack Kelly, seven, Rosie Kelly, five, and Flora Kelly, two, to the museum to take part in a mask-making workshop specially arranged for the half-term holidays.
Jack added: "Scrap Heap Challenge is my favourite program but I also like Blue Peter. I can't wait to watch them on it."
