Vintage "glorified chicken inspector" LITHO TIN TAB Button Pin Rare!

Vintage "glorified chicken inspector" LITHO TIN TAB Button Pin Rare! I do not have much info on this. paint has numerous but small scratch marks. Still high gloss as seen from the flash. From the mid-1950s to 1960's and rare. I have not seen another one. Does not appear to have been folded over. The coin in the photos is in the photos to show size and not included. Larger than a quarter.
