Yes, nice ones.

To me, the MK had a straighter seam (but....?) like one pictured here from Jill (2001). The other picture is Vitro Lucky 6 & Lucky 7 by Patry.

Very nice group!

Kind of similar to the Van Gogh also.

Here is my Big Dime Box (thick one) with Champions.

Here is a picture (2 views) of a Backlash that David Chamberlain posted and a "tag" (not sure if posted by David).

When I read this, I thought it was going to lead to "bye, bye girlfriend"

Gladding-Vitro was in business 1969-1982. I always thought these were made for the French in Canada. But, yes, they are common.

I always use this photo by Steve Cogdill, back in the day (2003).

My favorite cat's-eyes. Wonderful gift to you.

Maybe there are two parts to the stamp and only one part was done backwards.?

Here's one bag of 'em

I remember making my rent money playing pinball when I was going to college. Can't remember the name of the game but there were 25(?) numbered "blocks" and various patterns to win more points (and thus more money) (probably illegal for the bar to do but....it sold more beer).

"Marine" bags - and I could not find any Vitro bags with the name "Marine" like the Marine Gems mentioned. Exotic Gems, etc. but nothing with the name "Marine".

Very pretty Imperial types.

Porcupine seems logical - pic from Block's Sulphide book. Sulphide - Porcupine.pdf

Rich Maxwell posted this on the Vacor FB Board yesterday. I knew Pete had been seriously ill for several years. For those that don't recognize the name, he had one of the first marble chat boards - Land of Marbles, as well as his website with same name. He was really into Mega marbles that were sold in the US. He had an Excel spreadsheet with dates, pictures, etc. on each type of marble that was sold in bags in the US. He was aware of ones sold around the world but wanted to focus on the US marketed Mega bags. I never met him personally but we communicated over the years on Mega. Prayers for his family. Here is Rich's post. Hope just text me. "Hi Rich, It is with a heavy heart that I am telling you about the passing of my husband Peter Caparelli. He unfortunately lost his battle against the neurological, degenerative, progressive disease Spinocerebellar Ataxia Type 2 (SCA2). Please keep him in your thoughts and prayers." Hope Caparelli

Sad story there. Thanks for sharing.

Agree

Looks like it to me.

I'm not a contemporary collector but looking at Steph's name list of contemporary makers - under the BM initials are Bryce Majors, Boyd Miller, Brian Mortenson, Bill Murray and Brian Myers. There were none under BW initials.

I have a similar bag. Have not opened it (did not want to release the radiation....)

I'd be interested in what other long time Pelt collectors have to say. 15 years or so ago, the pictures that I posted by Guy and Chuck were considered to be bifurcated just like the OP and first pic in my post above. I have seen it narrowed down in recent years to just the base glass being the bifurcation. Either type is hard to find.
