It remains to place the postcard in one of the two notches of the support attached to the cover to be able to observe it through the lenses. Focusing is achieved by sliding the cover. For the state, note scratches, splits in the wood (in the corners), a lack on the lid. Our many photos allow you to appreciate the quality of the object.
