Here is a Beautiful pair polished Burl Wood Bookends, that were quite popular, and could be found in the study or many an office in the the middle of the last century (1950-60s).

The polishing on this set of book ends does a wonderful job of highlighting the beauty of the woods grain. We love the way the grain pattern lines up along the separation cut, along the top. 
Mother natures sculpting at its finest.

The dimensions of these book ends is  approximately 9 inches wide, 5 inches front to back, and 5 3/16ths tall. This set of bookends weighs approximately 5 lbs, the burl wood being very dense.

These would look just fantastic, as a detail decorating touch, in a home or office done in the Mid Century Modern Style.
