Superman in Spawn?

Anyone know what Spawn issue this image is from (and I'm assuming the second one is from the same one) . I'm curious to see what was going on and why Superman is appearing in a Spawn comic (without the trademark S of course since... you know... copyright).

...Kal-El was the first Spawn, what?

Please tell me that DC is not trying to buy out Image or something to that nature. I would hate to see the great independent works/characters go the way Wildstorm did.

@world_breaker_elmo: No, no. McFarlane used to do this kinda stuff all the time. This comic is from like 20 years ago.

Always wanted to ask how did you get your profile pic wish'?

Huh?

@wishiwassuperman: Spawn 10.

@lolzstastic: Thanks man....
