I actually knew nothing about either character until seeing the Netflix shows. I just finished Iron Fist on Netflix and that's what gave me the idea for the banner. I remember seeing this weird house ad (the Iron Fist one) as a kid reading other Marvel books and wondered what it was all about. I didn't know there was a corresponding Cage house ad until I started working on this banner. Might be worth picking up a TPB of this team.
It definitely is. I read them a few years ago and they are a lot of fun.
