Vintage Crow Owner's Society Button “Cancel the Holocaust” Badge Button Pin Rare

Unique button featuring a colorful crow design. Includes a rainbow and anti-bomb symbol. This is a vintage piece, I haven’t found anything similar online (thank god) but now it’s here. From what I understand is that the Crow Owners Society was a group from OR who were actively denying the occurrence of the Holocaust. (This is not my ideology, but apparently that’s a thing, sorry if you believe this is offensive, but this is material history)
