Batman Issue 175

The Decline and Fall of Batman!
While getting his picture taken outside of a haunted house, Dick Grayson is shocked to find Robin in the background of the photo when it's developed. With the help of Batman they stumble upon a mystery in which duplicates of themselves that can become intangible at will are helping crooks commit robberies.

After a few failed attempts at stopping these doppelgängers, Batman and Robin find a chemical that allow them to destroy the duplicates and stop the man responsible: criminal Eddie Repp who has built a special device that allowed him to create the duplicates.
