.....a bit of a stretch for the two issues that were featured (and that also hardly made Super DC Giant #S-16 of September-October, 1970....
....a giant; after all, it was little more than two issues!).
Still, it was two pretty interesting issues, with an edge and bottom of the cover by Murphy Anderson, two classic comic covers by Carmine Infantino and Ramona Fradon, and some additional material to make it worth a look back at!
Brave and the Bold #67
This story was also reprinted in the Brave and the Bold Annual #1 of 2001, and in black and white in Showcase Presents: The Brave and the Bold Batman Team-Ups #1 of 2007. This was the first of many Batman/Flash team-ups, and makes one think why is DC not collecting Brave and the Bold Team-Ups: the Silver Age (which could feature stories from Brave and the Bold #50-56, #59, #61-64, to accompany the Brave and the Bold Bronze Age Omnibus, which starts with issue #87)?
Brave and the Bold #57
A Metamorpho: Silver Age collection featuring his two solo B&Bs, a team up with the Metal Men, a team-up with Batman and the first 8 issues of regular series would be welcome (or perhaps a Metamorpho: Omnibus, having all 17 of Metamorpho's issues, as well as the B&Bs, including a few later ones, and maybe including his Action Comics and World's Finest Comics back-ups, as well as 1st Issue Special one-shot and Superman team-up from DC Comics Presents), would also not be unwelcome (and would cover most of his appearances before joining Batman's Outsiders).
...but, that drawing was missing a few folks, like Speedy of the Teen Titans (colored in Green Arrow's original costume colors), as well as having Starman and Black Canary (with Black Canary only recently meeting Batman in B&B), as well as Supergirl (who only worked with Wonder Woman, in B&B #63 at the time...and Wonder Woman was there, but in her Diana Prince look (as Diana had a few team-ups with Batman), also missing Batgirl, who worked with Wonder Woman and Batman in B&B #78 against Copperhead). Still, it is a great little drawing....
