Steel Vault

The album caption reads: " Steel Vault in which the finished Radium Salts are stored."  The vault was located on the first floor of the Flannery Building. After the closure of Standard Chemical, a bank (the Oakland Branch of the Peoples First National Bank and Trust Company of Pittsburgh) took over  the building . As might be expected, the bank found the presence of the vault convenient and used it.  Unfortunately, the vault was contaminated. 

The following photo (courtesy of Joel Lubenau) shows how the vault looks today, some ninety years later.
