Every day, millions of people depend on their city's metro to travel to and from work and to get around in general. Therefore, it kind of makes sense why so many cities across the globe have decided to step it up and make their subway systems more attractive. In London, for instance, a program called Art on the Underground commissions contemporary artists to create and display paintings, photography, and other works throughout the Tube's stations. In addition to exhibiting artwork, however, Art on the Underground will soon offer commuters turned art enthusiasts pieces to buy and collect.

Next month, Art on the Underground will launch "Print Shop," its first ever pop-up shop located in Piccadilly Circus Underground station. The shop will offer 15 sets of signed and numbered, limited edition prints from renowned international artists from April 8-19, 2014. Art on the Underground and Own Art are working together to launch the pop-up shop; both initiatives aim to provide aspiring art collectors with a chance to get their hands on affordable art in a non-gallery setting. Additionally, the fifteen sets of prints on sale were commissioned by Art on the Underground for 15 for 150.

Basically, 15 for 150 offers works of art by 15 premier artists to celebrate London Underground's 150th anniversary. Best of all, 15 for 150 is for a good cause. All profits will go towards Art on the Underground and help support the program in the future. To find out which artists will be taking part in 15 for 150 and for more details, head over to Art on the Underground's page.
