Flash (Barry Allen)
The name "Showcase" comes from a 1956–1970 DC anthology series often used to try out new characters. "Showcase" featured the first appearances of the Silver Age Flash (Barry Allen), Green Lantern (Hal Jordan), and the Atom (Ray Palmer), among other characters. That series was revived briefly in 1977–1978 and its name was used again in 1984–1985 (for "New Talent Showcase" and "Talent Showcase") and 1993–1996 (for 12-issue anthologies, "Showcase '93" "et al."). The title was also used to reintroduce characters in the "Action Comics Weekly" series in 1988.
