Batman and Robin and Plastic Man

Neither Batman (introduced in 1939) nor Robin (introduced in 1940) wore masks that covered their nostrils or mouths. In “The Dawn Patrol Crimes,” though, they removed one that did. Though, yeah, that’s not why Mr. Smythe was wearing it. Detective Comics #123 (May 1947) © 2020 DC. Then, there’s Plastic Man. Were his goggles even a mask at all? Or just part of his entire plastic form? Police Comics #3 (October 1941) © 2020 DC
