Bought this on ebay today for 99p. It's a decorative panel rescued from a now smashed up piano. It measures 17 1/2" by 7" with mother of pearl inlay. The piano was supposedly bought from The Ideal Home Exhibition in the 40's but the design is much older than that so I suspect the story (unless due to the war second hand goods were on sale).
I'm sure I'll find a nice little spot for it here in the part of my house where my own piano is housed. My cottage has modern additions but the core of it is 150 years old with exposed beams so where my piano is is all old-fashioned with a mix of Georgian, Victorian, Art Nouveau and contemporary pieces. I enjoy finding bargains and making them work together somehow. Nothing's posh but I enjoy my little 'treasures' as much as if they cost a fortune!
