The white label Porky Pig was distributed by a company run out of Waltham MA called Thumb Monkey. The story I was told when I went there in person is that companies unloaded surplus games to them at a greatly discounted rate, but without retail stickers so that they couldn't resell them for a large customers couldn't attempt to return them to a retailer. The labels were applied after the fact and often have funny misspellings (Like WF Wrestlemania.

Here are some that I picked up in person:



Cool enough as collectible oddities, but only worth about $2 or so.

The two Genny games are prototypes. Unnecessary Roughness is probably around $25-$50, the other title I can't make out. The title makes a huge difference in price, any chance at a clearer picture or the name of the game? It's certainly on a dev PCB, so it's 100% a proto, I just can't tell which one.

Hope this helps!
