This is a wood plank 2ft square by half in thick painted black. There is a unicorn made completely of carpenter nails, with an artist signature that looks like OJ Kraft, 68, but not 100% sure. It has been hanging on my grandparents wall since the 70's. no one in my family knows where its from. It was given to me when they passed in 2010. I don't know anything else about it.
Thank you for contacting Mearto with your appraisal inquiry. So that I may best assist you, can you please upload a few better images of the signature and the reverse side of the artwork.
With kind regards,
