No, absolutely not!!!!!!!

It's only
personal speculation by Pip and me, given Eric Dobson did design after MH left, and it is known that the "Tiger" pattern is his.
Nothing is known about the shape. Nobody has been able to track Eric Dobson down since he left Mdina, despite a great deal of effort being put into it.
Very little Earthtones was made while MH was still there, but it IS his design.
After MH left, experimentation continued, designs were developed from existing ones, new designs were made. It's in the nature of Art Glass to develop. :thup:
