Inside the Colourful Crayola Factory

Photographer Bryan Derballa, 32, captured the incredible crayon-making process during a visit to the factory in Easton, Pennsylvania.
Crayola, which was founded in 1885, uses a complicated production line to make the iconic colouring sticks.
Mr Derballa's pictures provide a fascinating glimpse into the creation of the crayons which certainly take many of us back to our childhoods.
