I'm unable to verify the existence of a work by Edvard Munch with the title "Alpha and Omega: The Wife Omega and the Donkey." While Munch did create a series called "Alpha and Omega" around 1908 exploring themes of human relationships and animal symbolism through lithography, I cannot confirm this specific work or provide accurate details about it without reliable documentation. I recommend consulting museum collections, catalogues raisonnés, or verified Munch archives to obtain factual information about this particular piece.
