Yates has travelled from Colorado in the US to put paint to wall as one of nine finalists in the International Mural Fest.

It is the second time Yates has taken part in the competition at Sheffield's Mural Park, previously with a Goldilocks painting, after hearing about it in Scotland.

She said her mural Stamp of Joy featured two girls, one from prehistoric days and the other modern day.

``They are working on painting one of the buildings of Sheffield together with one hand and they are both putting their stamp on the town with the other,'' Yates said.

Each painting in Mural Fest responds to a poem called Island Life by Rees Campbell, which Yates does by featuring the girls in the window of a map.

``I wanted to include different parts of history all into the same thing,'' Yates said.

``So I figured it had to be a magical world . . . and Mount Roland is in the background and I've included some ancient language.''

Yates said the competition had been difficult this year with the rain and excellent artists, but she was hoping for a good result.

``My hands were shaking and they were all tightened up from the cold yesterday,'' Yates said

``And the wall itself was really cold and kind of dewy.

``It's a really close race, there are so many good designs, but I'll just hope for the best.''

Mural Fest continues every day until Saturday when the winners of the $15,000 first prize, $5000 runners-up prize and two people's choice awards will be announced.
