Extremely difficult Hank, the highest graded is a 5. One of the toughest sets of the 1960's. These were issued in Canada in 1968 and were the same as the US counterparts issued in 1967. The only difference was the poster number and at the bottom it says printed in Canada vs USA. It is thought that the print run for these was roughly 3-5% of the US. Anything you can find is torn or split at the seams. Most of the set pops are single digits.
