Thrift store finds are the best!

Found this recently in a second hand setting. No artist signature, no date, but framed elegantly (the frame is super heavy), and seems to catch the eye. Who would go through all the trouble of painting, framing, and hanging a painting but leave off their signature? Made me wonder about the artist... was it just a slap in the face to copyright laws? Was it just a slight overlook? Did they do it on purpose and if so what reasoning did they have? Do other artist practice this practice? Do people just leave random paintings unsigned at thrift stores? Hmmm. I felt bad for the lone wolf and so he now resides here at home with my nerdy lion. They were destined, I guess. Image isn't subject to copyright that I know of so feel free to use it to your liking. Kspeaks
