WARNING
ALL ITEMS OF VALUE ARE PERMANENTLY MARKED WITH OWNER’S DRIVER LICENSE NUMBER.
STOLEN ITEMS WILL BE TRACED BY THE ST. LOUIS POLICE DEPARTMENT
Etching tools which will mark your valuables with your driver’s license or social security numbers are available at the SDCC office, 6008 Kingsbury, V02-5122. A rental fee of $1.00 is charged, also a small deposit you get back when you return the tool. Stickers like the one shown can be picked up there too.
This method of identifying personal belongings is proved to have greatly reduced thefts and break-ins in other areas. Call and reserve the use of an etching tool today. They are easy to use, like a pen or pencil.
