Not sure I understand the matter, but what is the link - a modern printing with the old board. Order of three pieces, and you print it straight right now for 52 euros per sheet.

By now it is clear that there - copy.
 
So there is a chance that I oreginal :D>

Difficult to see from the photo, but not feeling that your print and the one on the link, not the one printed board.
Separate and sort the parts are similar, but not identical: armrest, proborchik in her hair, even facial features.
But maybe it's so distorted picture.

You correctly noticed, there are differences. Єto I immediately considered , and the size is sensitive not match.
 Provenance can something podkazhet .
 This engraving of a large folder turn up the old pre-war lithographs (approx. 1870 - 1910), which was brought for sale people who bought an old house , and she even gives a little damp.
Also, try to find it oreginal to compare and know the size, but to no avail ...
