Highly rare vintage 8x10-inch black and white publicity portrait as White Bull in Disney's 1958 adventure film Tonka, boldly signed and inscribed in blue felt-tip pen in the 1970s. In good condition, with a minor tear to the top border and scattered mild, but noticeable handling bends in the light background at the right, slightly detracting from overall appearance. In 1977, gifted juvenile star Sal Mineo was tragically stabbed to death, aged only 37 years, by a drifter named Lionel Ray Williams.
