These prints are much smaller than all my other lithographs and, as of 2024, I am framing them differently - see image below: 

They are 'floated' within the window of a much thicker mount -  again Arqadia Minuet mount board but 2.2mm as opposed to 1.4mm. The profile of the black-stained ash frame is the same as all but the largest of my lithographs ie. 22mm deep with a 22mm face.
