C1973 Can the Eavesdropper be Used as a Phone?
Red Robin had only told them about an old matter, because the mask was too strange. If the wearer would not be seen by others, it could be said that it was very useful. However, after wearing it, they could not see others. It was simply a joke. They did not know why there was such a thing. After a series of tests, the batman did not find it, so he put it aside with other "memorial items"
