Studio stoneware bowl, Aldermaston painting style, TD, CH or DH mark

Studio stoneware bowl, Aldermaston painting style
Cll mark.
1970s look

How big is it? That is a very clever decorative style,but I do not think it owes much to Aldermaston. First thing I thought with that image in the centre is a Seagull against the sun at dawn or dusk. A owl aimed at the tourist market?That base looks good as well. It is so irritating. If your pottery is so good. Why not mark it properly??

Thanks Philpot. 10” bowl. The design in the middle is a bit like a bird but not quite.
