Born on the 7th of March 1967 in Hertfordshire, Sibthorp went through his early life with a certain artistic eye that was to carry him to great heights. This passion brought him to study Illustration at Kingston University and in 1989 he graduated with Honours, following this he began an artistic journey exploring the changes that movement afflicts on the form.
For the next few years he worked taking on commissions, mainly for corporate brochures, magazine articles and book jackets. However in 1992 his line of work took a more dramatic tone as he exhibited in his first solo show at the Stable Gallery, Wandsworth in London, aptly titled 'In Motion'. Following this, five large scale pieces of his were acquired by a Private Sports Club for their flagship club in London as part of their permanent collection.
As more and more high profile commissions rolled in, Sibthorp found himself taking on commissions for The Evening Standard, BP, BT and a range of other magazines. For his talents and contribution to the art world, Sibthorp was awarded several Certificates of Excellence by the magazine Communication Arts and in 1997 he was featured in three of their CA Illustration Annuals.
Today, after numerous shows, notable commissions and amounting a variety of public and private collectors alike, Sibthorp has settled down in the United Kingdom and continues to paint to this day with his works exhibiting across the country and his pieces being distributed all across the world.
