Beautiful Keen Kutter Knife Sign Circa 1930s

This is a beautiful sign to me. I don't own it but look at the colors! The logo is in the bottom left-hand corner. It features a woman using one of their knives to cut what looks like meat. What is interesting about this sign is that unlike the other advertising ones i've seen, this one actually has the item numbers below the pictures. I'm guessing this wasn't metal, as the corners are kinda furled upwards.
