That's odd... Nothing I've seen before. It might be a handmade thing.
Yeah, they are handmade. They're ceramic lamps that could be made with a mold available from stores back in the early 80's I believe.
They're pretty quirky looking, that's why I've got two.
The lamp Dale won for me actually looks different from pics of the ones I'd seen that were (supposedly) sold in the US. The one Dale one looks much cooler, actually, and more Star Wars-centric while the other ones I saw basically were a simple Lava Lamp with a little ROTS logo on it.
Jesse, can you post pics when you've got it? I'm really curious to see what it looks like.
