As a promotion for US rock band Kiss' concert in Helsinki next week, the towering, iconic four granite statues at the entrance of the central railway station have been adorned with the group's face-painted masks.

While Kiss may have sometimes struggled over the decades, the group has mastered the art of corporate marketing and merchandising. The band - despite changes in fashion and their lineup - has reportedly sold more than 100 million albums worldwide during its 44 year lifespan.

The band's latest promotion in Finland involved four fans who won the chance to paint the large masks, as advertisement for the upcoming Kiss concert at Helsinki's Hartwall Arena on May 4.

The deal was arranged through cooperation with state railway company VR, Helsinki's Radio Rock and the local Kiss fan club.

The masks will be removed the day after the concert, VR says.
