I wish I knew what hand created this 18th-century portrait of a "Dame in blau-grünem Kleid mit Bortenstickerei und Spitzenkragen, mit Facher und Hundchen" (translated from German that's Lady in blue-green dress with ribbon embroidery and lace collar, with fan and small dog).  What seized me was its prime example of how dogs and their people look alike after awhile.  I know it's hard to see up above, so I tried to get a little closer in:

Bonus!  This portrait came with the husband version, complete with Hund - want to look?  Here.
