It is time for episode 21 of Mandatory Marvel & DC, a show from the Comics In Motion network that looks back at the very biggest and best stories from the annals of the Big 2 - Marvel and DC!

Each episode, Max Byrne will be joined by a special guest to enjoy a chat about that episode's subject matter, talking about what we love about these top tier titles!

For this 21st instalment, we look back at the classic Green Lantern/Green Arrow: Hard Travelling Heroes from DC Comics. Written by Denny O’Neil with art by Neal Adams, this classic story examined the state of play in America at the dawn of the 1970’s, looking at social injustice, racism and many more issues.

This week, Max is joined once again by the amazing Tony Farina, an amazing writer and, of course, host of the fantastic Indie Comics Spotlight podcast right here on the Comics in Motion Network!
