Brazil Batman Superman World's Finest EBAL cover 1970

Brazil had DC and Marvel comics too, in the Silver and Bronze ages. Don't know too much, except they reprinted US books in Portugese Spanish. Many of these covers were evidently US book's covers on tracing paper, glued to board. This, however, is all original art by some very capable Brazillian artist. I also have the color guide on tracing paper. Paper quality is lightly tan on board, tape is flaking. Piece is Approx 13" X 9 1/2 "
