This is an example of a “Double Vision”
One side has a figure cut in (in this example a swan ) now turn the figure 90 degrees and you see a completely different figure, in this case a Ballerina.
Hence “Double Vision”
It’s almost like 3D sculpture with 2 different subjects.

These are made of Basswood with an oil finish. The base is 1 1/2″ square and they vary in height from 3″ to 4 1/2″
