The Sliding picture frame is constructed of black-colored wood and is a great conversation piece. This hands-on frame features six 3x3 photos in three rows. The front and middle row of pictures slide from side-to-side in their own wooden track. The back row of three pictures is static and shows through only when the front or middle row is moved. Each picture is framed in it's own white mat with a glass front. The front and middle rows can easily be removed by a spring-loaded system to make changing pictures a snap.
