The Flying Batcave debuted on the cover of Detective Comics #317 in July 1963. This was the sort of goofy stuff that filled Batman comics in the 1960s, but when I stumbled across this as an 8-year-old, I spent way too much time trying to figure out how I’d build my own version when I was a crimefighter.
Eaglemoss’ diecast version that’s part of their Batman Automobilia series looks fantastic.
