I am not sure when they stopped screen printing them, and I may be wrong, but I do not think they were screen printed in 1956. The newer ones definitely are not screen printed. At least none of the ones I have are, ranging in years from Fistful of Dollars to Road Warrior. The only ones I have seen side by side for comparison is my Mad Max 40x60 next to a Max Max 1sh and Road Warrior 30x40 next to a Road Warrior one sheet. To my eye, the card stock printings look much better. I just do not have the motivation to get the others in the one sheet format because of the cost. I have seen the Blade Runner next to a Blade Runner rerelease, but thats not really a fair comparison.
