A favorite image in my virtual collection depicts this gorgeous pair of figures of a harvester and his lady, made by the Leeds Pottery circa 1790. Leeds figures are readily recognizable--I have recently written on that topic--and usually no mark is needed for an attribution.
Why there were so many design modifications I do not know. Notice this pair of companion groups from the pot bank that operated in Tunstall.
While I question all the attributions, I concede that Ralph Wood probably made more than one pair. I think the first pair below is almost certainly his handiwork, and the second is very likely to be his.
