It's more retro helmets galore from Sean Bull

Sean Bull, livery and helmet designer extraordinaire, just put together another portfolio of intriguing helmet designs.

Last month, Sean applied modern drivers' motifs to a vintage helmet, but this time he's done the reverse, applying helmet liveries from a bygone era to a modern day lid.

Check out the collection which highlights the simple yet striking retro designs. We'll admit we have a soft spot for the Senna and Hunt helmets. What's your favourite?
