Africa's artists catch the global eye

Giles Peppiatt, from Bonhams in London, had good reason to make the trip to Nigeria's financial capital, Lagos, for the auction house's next sale of African art - a glut of potential buyers.

On a recent visit, he described Africa as "one of our hottest properties on the art block".

"In some ways, Africa is the new China when it comes to art," he added. "We are investing time, money and people to maintain our presence in this market."
