MAD in Norway has gone thorough four publishers since it appeared in 1971. The first edition only lasted for a brief 8 issues in 1971-1972 and then stopped. The second edition picked up 9 years later and lasted for 13 years. The third editon followed the next year with a short run of 4 issues. Then the fourth publisher tried one last time (so far) in 2001. I have only seen 6 issues from that run and I assume that was the extent of that effort.
There are several Norway-only covers in this series. Some of the covers were shared with Sweden and Denmark.
