looking for media buyer / PR (London area)

Question

The exhibition 'From Memling to Rubens at the Royal Hospital Chelsea' opens in March 2022. It is a reworking of the exhibition that ran a few months ago in Tallinn (Kadriorg Art Museum). I am looking for an agency in the London area that can handle the media buying and PR for this.

The magnificent exhibition introduces the abundant 15th‒17th century Flemish art collection of The Phoebus Foundation, and provides an overview of the versatility of the Belgian art culture of the time. The display juxtaposes the long tradition of religious art and portraits reflecting the importance and rising self-awareness of the individual with moralising satire and political comments. The richness and curiosity of the era is reflected in the art cabinet, and new discoveries and the spreading of knowledge are the goals of the print cabinet.
