Neat vintage aluminum sign. It seems to denote property line between B.N. and another property. IND could mean a specific industry, or could mean Individual. I believe B.N. stands for Burlington Northern, now known as Burlington Northern Santa Fe, or B.N.S.F.

Good Condition with dings, scratches, and wear. Unpainted.

About 8 1/8" x 6 1/8" in size. 

Will be shipped between two pieces of cardboard with "Do Not Bend" stickers
