Jean DERVAL (1925-2010) Rider with shield Large subject in brown enamelled chamotte clay. 57.5 x 47 x 21 cm. Signed on the reverse Note: At the end of the 1960s, the artist's taste was marked by a choice of pieces in more austere colours, at the expense of the more colourful earthenware of the early years. Jean Derval then turned towards architectural ceramics with a vision of a sculptor rather than a potter.
