This is the cover of the June 1969 issue of BDP Preston in-house magazine ‘Contact’.
BDP was founded in Preston and pioneered a team-based, democratic approach to building design in the era of the mandatory fee scale. In this illustration entitled THE INTEGRATED TEAM the BDP ethos is affectionately satirised.
I believe the artist was Peter Jones, an architect in the BDP Preston office. Note the representation of the QS ‘CALCULUS ABACUS’ in what appears to be a dunce’s cap.
