John Crane has collaborated with BonusPrint to create a cutest photo competition - parents are being invited to send in pictures of their children with toy fire engines.
Every entry will recieve a prize of a BonusPrint lunch box featuring their photo while the winner will collect a complete Pintoy Police Series.
John Crane is celebrating sales of over 70,000 Pintoy Fire Engines since launching the toy in 2007.
Head of marketing at John Crane, Helen Davis, said: "It's an honour for such a large multinational company to offer to partner with us and proves just how far John Crane has developed over the last three years."
Speaking about the social media campaign, Davis said: "All three companies involved will be tweeting and using other forms of social media to promote the competition and it’ll be interesting to see how many entries we receive.
"Of course, by using social media we can track where consumers are clicking, how long they are staying on each of the three sites and of course, most importantly, where they are buying John Crane toys."
