CPLG Sport has added to its roster, with the RFL appointing it as the exclusive licensing agency for the Engage Super League.
The three-year deal means the Hammersmith-based firm has secured the rights to use the Engage Super League logo and the 14 club crests on a range of merchandise and apparel.
"CPLG Sport will be able to maximise the huge potential offered by the Engage Super League brand and we are looking forward to what promises to be a very successful partnership," said the RFL's commercial director, Paul Kimberley.
"We're delighted to have them on board as licensing agents."
CPLG Sport's Nicola Lord added: "Super League is a fantastic property and we're very excited to be involved. The brand can work across any number of categories and in the initial phase we will be looking to develop merchandise in categories such as apparel, interactive, souvenirs and publishing."
