New Scientist has asked readers to choose between these works of art for a chance to win a pair of work shirts.
The winning shirts are available for free in a selection of sizes from 6 to 16.
They’ll be available in two colours: black and grey.
They will be shipped in two weeks, with a maximum order of £150.
The winner will be notified on 29 June, and the winners will be contacted via Twitter.
There’s a chance of winning too.
In the past, readers have won a variety of other prizes, including a new shirt design, new style book, and a book of stories.
New Scientist can reveal the winners at a later date.
