the bocage was introduced to earthenware figures about 1810-1820; it is difficult to pin-point the date more accurately as there are no subjects which offer a close date, nor are there any marked pieces from an early short-lived company
First, we know bocage figures were made by Ralph Wood. Ralph Wood died in 1795, so bocage figures were being made by that date.
Remember, Ralph Wood died in 1795, so is this Ralph Wood bocage figure (and others like it) not proof enough that bocage figures were made in the eighteenth century? Surely so! But what if you absolutely MUST see a datable maker's mark to be convinced? Well, relax, I can still prove the point.
Life would be boring if we did not learn and grow. And so it is with our knowledge of bocage figures. We now know that they were being made in the 1790s for certain---so roll back your mental clock on bocage to that date.
