Vintage school educational chart "Stegosaurus a Allosaurus" on hard paper, painted in 1959 by Czech painter, book illustrator and palaeoartist Zdeněk Burian, whose work played a central role in the development of palaeontological reconstruction. Originally recognised only in his native Czechoslovakia, Burian's fame later spread to an international audience during a remarkable career spanning six decades (1930s to 1980s). He is regarded by many as one of the most influential palaeoartists of the modern era, and a number of subsequent artists have attempted to emulate his style.
