I appreciate that this is a long shot. I have done a lot of google searches on this!
We bought a picture of a hare at a craft show at Calke Abbey (NT) 2 years ago. It wasn't expensive but nor was it cheap, £80.
It is signed Anna or Anne Rosecroft, Rosescroft or Rosacroft .....???
She was a middle aged lady (or maybe a bit older?) and I seem to be remember she was quite hip.
I did take a business card but have lost it and now I really want to order another painting for my DH for Christmas ... !!
Does she ring a bell with anyone?
