Mystery bucket

This bucket or pail has been in our family for decades. It's origins are unclear but it was under my mom's sink and now mine - always with potatoes and onions. It says "Paper Mamph" but I have no idea what it means - especially with the lobster image on it. I Googled the phrase and that was no help. The most hits for "mamph" is some kind of slang or short form for methamphetamine which I am sure is not what I'm after. I had thought it meant paper bucket or bin but what about the lobster? It doesn't seem like a lobster pail, either. Any ideas?
