1968/06 Flash # 180, page 15 by Ross Andru & Mike Esposito. Costume ejects from ring.

This page was published in June 1968, penciled by Ross Andru and inked by Mike Esposito. This was the artistic team that replaced Carmine Infantino on the Flash after his 11 year run. Ross & Mike had a relatively brief stint (issues 175-194) because they received heavy criticism from Infantino fans. They fared better on such titles as Wonder Woman and Metal Men.

Keith Dallas used the panel from this page where Barry Allen is shown ejecting his ring in The Flash Companion (on page 69) which was published in June 2008. The companion is a great read for any Flash fan.
