The Natural History Museum in London is looking for two creative agencies to work on different remits.
One agency will work on sales and communications objectives and the other on developing brand campaigns.
Winning agencies will have to demonstrate digital expertise, knowledge of the tourism market and experience of working with entertainment brands. Head of marketing at the museum is James Bailey.
The Natural History Museum appointed Krow as its advertising agency in June last year after a review held by the AAR. The agency has worked on projects such as a campaign for the Charles Darwin 200th anniversary exhibition.
The new Darwin Centre is due to open at the museum this autumn.
In the past Isobel has also worked for The Natural History Museum on a project-by-project basis.
