When the cab was serving as a stationary exhibition space at art galleries and events, however, Brown would often act as de facto docent for the collection.

In 1999, Brown approached Stolper with the idea of exhibiting art in the spaces reserved for advertising in his traditional London Black Taxi, and Cab Gallery was launched in Hoxton Square on 24 September 1999.

On the fold-up seats were two text pieces by Peter Liversidge, who became a regular contributor to the project and whose collected proposals were later published in book form.

[1] Also on display at the launch were All the animals, an embroidered cushion by Abigail Cohen, from Swiss Cottage to Soho and back, a book of drawings by Susie Hamilton, and Cab Gallery Greeting, a sound piece by Jessica Voorsanger.

The success of the launch led to other artists becoming involved and invitations by galleries and art event organizers to participate in their openings.

In mid-2000, the Bob and Roberta Smith exterior artwork was replaced with Sunny by Alex Katz, the American figurative painter.

In 2012 Brown donated the entire Cab Gallery archive including artwork, correspondence and ephemera to the Special Collections at the Library at the Chelsea College of Art & Design.
