Here's a cover gallery of my complete run of Page Publications' Super-Villain Team-Up:
Super-Villain Team-Up #1, c.February 1978
Super-Villain Team-Up #2, c.September 1979
Super-Villain Team-Up #3, c.May 1980
Super-Villain Team-Up #4, c.mid/late 1980
Super-Villain Team-Up #5, c.February 1981
Super-Villain Team-Up #NN, c.May 1982
The first two issues are regular/magazine-sized issues, and the rest are digest-sized issues.
The publication dates for #'s 1, 2, 3 and 5 are as accurate as I can manage at the moment with the data available, but I'm pretty sure they are accurate within a month. The date for #NN is based on a newsagency marking, and although it is likely a 1982 issue, it is possible it is from 1983.
As discussed before I do not think there was a Super-Villain Team-Up #6 with new material. The 'excess' material was published in The Champions #6 Black Panther #7.
Super-Villains Team-Up #NN is the only recycled edition I am aware of, but it is possible more exist.
