Fantastic USA set of 50 trade cards featuring dinosaurs of the Mesozoic period issued by Redstone Marketing in 1993 . The set comprises 46 colour dinosaur cards plus 4 glossary cards . Each dinosaur card has detailed rear text relating to the featured dinosaur . The cards each measure approx 3.5 ins x 2.5 ins and are on good quality thick glossy card . These are in excellent condition as shown on the scans and I am also offering one complete wrapper in which the cards were originally offered for sale .
