Abstract
Abstract An apparatus to facilitate the learning and practice of realistic free-hand drawing and painting. Instead of paper or canvas, a panel of specifically configured, relatively thin, film-like, transparent material is used. Such transparent panel is temporarily secured to heavier, rigid and also transparent panel while sketching, drawing or painting is being done on its face, using specifically configured and modified artists materials. Specifically configured supporting apparatus adjustably supports, positions and maintains such panels of clear materials at the desired proximity in front of the artist, while he sketches, draws or paints on such transparent panel whatever he sees when looking directly through it. Additional assisting means are provided for his optional use.
