Legendary artist George Perez posted the following commission piece on his Facebook Page which features the 1970s version of the Avengers taking on the original New Teen Titans.
Looks great as usual.
Just finished a major commission piece featuring the 70s version of the Avengers battling the original New Teen Titans (with Red Star and Speedy added) for a very patient gentleman named Wayne Osborne. This piece was too big for my scanner so, hopefully, this photo will be clear enough. Next will be another set of smaller pieces before I get on to another multi-character large commission.
