I love rust.  I found this and was going to use it in my yard but never have.  Just seeing if anyone has a better use for it first.

This antique cast iron fireplace architectural surround door is a rare find from the 19th century. The brown color and arched shape add to its historic charm. It measures 16X10X2 and is a must-have for any serious collector of antique original pieces. The surround mantel type and pre-1890 decade make it a unique addition to any home decor. The material used is cast iron which adds to its durability and strength. This piece is a true reflection of the authentic craftsmanship of the past and will make a stunning addition to any home.
