ABSTRACT:
A copying easel for copying three-dimensional objects including a support frame, a copy frame rotatably attached to the support frame and an open sighting awning rotatably attached to the support frame. The copy frame is constructed to cooperate with the support frame to support the device during use and includes a rigid, transparent copy base material over which is placed a removable, transparent, flexible copying medium upon which the copy is made. The sighting awning defines a sighting opening to view the object through the transparent copying medium and the transparent copy base. The awning further has sufficient thickness to block the vision of the unused eye and has two positioned indentations to accommodate the nose of the user depending upon which eye is to be used.
