CPLG Sport has brokered a series of new deals for West Ham.
Joining the programme are UR In the Paper for personalised photographic prints; USBMAN for West Ham branded USBs; and Kamtronik for football board games.
In addition, New Era has extended its caps licence, while Bafiz has renewed its existing footwear deal.
Over 35 licensees are on board with the club, including Danilo, Aykroyds TDP, Pyramid Posters and Home Win.
"West Ham United are an incredibly popular club with a strong domestic and international following, and over 600,000 fans listed on the club's database," said Gary Jacobson, commercial manager at CPLG Sport. "This makes them a very attractive prospect from a licensee's point of view and the programme for the club is set to carry on growing."
