reminder again

i had an idea for reminder again after looking at one of my original scrap pieces.  similar to reminder, i wanted to expand on one small idea from an older piece.  materials here included found plywood backer, poplar from an old desk i hauled home and disassembled, salvaged 1/2" baltic birch plywood (which someone had painted with black chalkboard paint), 1/4" plywood, copper nails, slices of the tape from an old tape measure, maple (legs from a chair i got on the sidewalk), hemlock and black walnut remnants and little colored shapes of wood (thanks, mom!).  and adhesive.

approximately 20" in diameter and 4 1/2" deep
