Design for a frieze and detail of balusters, perhaps for C. R. Cockerell's unexecuted competition design for the Royal Exchange, London

NOTES: This sketch is one of a number of preliminary studies of English Baroque architecture made by Charles Cockerell in preparation for his watercolour composition 'A Tribute to Sir Christopher Wren' (1838). It was formerly part of an album of drawings entitled 'Ichnographia Publica', compiled by Cockerell from 1825 as a private 'scrapbook' containing his measured drawings, notes and studies relating to the architecture of public buildings. The bracketed numbers which accompany many of the sketches refer to the numbered 'key' to the engraved version of 'A Tribute to Sir Christopher Wren'.
