I always enjoy seeing a #16. I call it sneaky difficult to find in that you think this is an easier issue to find because you do see it for sale from time to time, but I find that it is the same 3-4 copies that are for sale and not an abundance of the issue. Your 16 is super nice Flex. I really like the green back ground.
This is the first and only cover showing "Mars, God of war."
Mars, God of War storyline details the adventures of the ancient Roman God. Each story showed him causing violent mischief on other planets. The interior stories were credited to writer Ross Gallen, and all drawn by Doolin (no Zolnerowich). The embodiment of evil, the spirit of Mars would "single out a man or woman who had evil in them," possess them, and run rampant until "the end of each story [when] good always triumphed."
The first appearance of Mars God of War was in Jumbo 31 (Zolnerowich cover starring Sheena) and then subsequent stories were all in Planet comics ineach and every issue starting in Planet 15 and went on until Planet 35 when he was defeated by a new storyline Mysta of the moon (One of my favorite internal stories for crossing over these two FH all-stars, a creative storyline, and some really nice art).
