ABSTRACT:
A postcard assembly comprising a first, second, and third sheet, the sheets being arranged one on top of another, with adjacent sheets removably attached together. The first and second sheets have first and second upper and first and second lower surfaces. The first and second lower surfaces comprise pressure sensitive material, wherein pressure on this material causes a visible mark to be formed on a sheet positioned below the first or second lower surface. The third sheet is adapted to be mailed as a postcard with the second sheet removably attached to the third sheet and with the second sheet obscuring any visible mark on the third sheet.
