It is double sided. So its quite large and heavy. The sign itself is about 27 pounds. Its 41″ x 32 1/2″. It has wear, rust, chips, looks like the corner got/was bent? . It should clean up more but I didnt want to try and ruin it. I dont know if its porcelain as I dont know the difference. It comes as seen.
