1920' - 30's Standard Oil

For your consideration is a 1920' - 1930's Standard Oil Co. Solid Brass Large Oil Barrel or Drum Tag. This tag was removed from a large steel oil drum that was badly rusted and the steel rivets that held this tag in place were cut off to remove it (see picture of back to see cut marks). The tag is heavy solid brass with 4 steel rivets and I have not tried to clean it, but I bet it would polish up pretty cool if you wanted to remove the tarnish. The tag has a bend to it and Does not lay completely flat. I am guessing the bend happened when it was removed from the barrel?  The tag measures about 9" inches long by 4 3/4" inches tall. The tag reads; "NO. 4902 RETURN WHEN EMPTY TO STANDARD OIL CO MARYSVILLE CAL". Please review the pictures to verify the condition of this rare and unusual gas and oil collectible. I like to consider offers, so don't be shy about making one.
