Geoffrey Godden notes that Mellor's name is woven on several bookmarks, but was probably not manufactured by them.
With the donation of the image of bookmark ome4 (see above), closer inspection of the design and weave is possible.
The weave quality and layout is un-like any of the Coventry weavers, and is also unlike any other weaver's work that I have seen.
It would seem to me that Mellor was in fact the weaver of this silk, and is not the work on any other manufacturer.
