A device to make annotations on a removable or fixed background is described, over which it is desirable to make annotations leaving it intact; When the background is removable, the device comprises an upper transparent and smooth film, with closed pores to make annotations with dry erase markers and a back cover attached to the upper film leaving an inlet through which the background is inserted, such as pre-printed sheets or radiographies. When the background is fixed, the device also has a mounting tab to be placed on said background.
