Tom,
The Mexican flag eagle in your link has a very similar pose but in reverse. I did find this 30 miles north of Gonzales, Tx the birthplace of Texas Independence, or so they claim. I wish there was more detail on the skillet. I know I haven't cleaned it completely since it still rubs black on my finger. On the other hand the pitting may have damaged it too much. There isn't much rust, just lots of thick black baked in crud.
