This is awesome, the only one I've ever seen, and I don't even know from which publication it came. It is an ad for chicken feed featuring the Alice in Wonderland feedsack promotion.
Based on the date on the bottom of the page it must be some sort of monthly publication, and it is oversized, page size is about 11x14, and this is page 55. It is newsprint rather than glossy, and it has browned considerably; the scan above has been heavily photoshopped by me. If anyone has any idea from which publication this came, I will be in your debt.
