Thought my dad was digging up one of his ‘junk’ signals again, turned out to be big iron highway sign folded in half! He unfolded it and put it through electrolysis, and I primed and painted it back to its original colors. Based on provenance & the early stamped design (later signs were embossed/raised), it is likely from the late 1910s-early 20s- just before Kansas had official ‘state highways’ (1926)! Also of interesting note, the square nail holes in the sign.
