Typographer's Marks

Hi all,
I'm tying to find a good handful of typographer's marks
I have Jenson's mark

and I'm certain I've seen Garamond sign work with an anchor & fish but I can't find it anywhere.
Did Baskerville have a personal mark? The Didot lineage, Pietro Bembo, Pierre Simon Fournier?

There is no start date and no end date to bookend my request. But I guess I'm looking for the legends of serf development.


Font or clip art?

I keep coming across these flourishes but can't seem to find where they originated. I assumed they were Dover clip art since they have a vintage or antique look, but cannot find them in any of their ornament books. Perhaps these flourishes are a font... Does anyone know where these specific ornaments are from?
