Imperial is not a manufacturer. Imperial Toy Company, previously out of the L.A. area, is a packager of marbles. Back in the late 70's & early 80's, they packaged Vacor marbles. Then, they found cheaper marbles in Asia, like the ones you posted, and started buying them. As we don't know manufacturers names from Asia, the collecting community starting calling these marbles, generically, Imperial. Here are a few bags/package pics.

Welcome. We look forward to seeing your collection.

Couple of my bags

For info

I have not seen one nor do I have any pictures of one.

It's great that you got to go to a show. Nice marble finds, too!

Agree

I'm back to the possible MK ID on these. I could not find good foreign examples of 4 vane crossthru types.

Left and right remind me of foreign made marbles - Mexico or Japan. Middle one?

Cool looking marbles!!

Welcome back to the Board.

Agree

Agree

I have not seen that name. Have seen Bonux and Ajax. Craig has had some odd ones like that from Europe - maybe he will know.

Just saw this message - no, I don't have any bag pics.

Probable Vitro Opal

Pelt Rainbo

Same here

And the upcoming Reno Show - best on the West coast and a good vacation spot for the rest of you in the marble world.

Yup

Agree

Maybe

First one just a Rainbo. 2nd one maybe one also.

It could be - a couple more views would help - also what size?

He has only done the one book. Since it was a fairly limited printing, the price has skyrocketed.
