The 4th one is a doozy! LOL

I rarely look under magnification but I can see where Cheese is coming from - it does look iffy although I can't imagine someone using the plain marbles... Plus, I have never seen that bag or picture thereof before.

Vitro Whitie - here are a couple pics of others.

I have to disagree with Chad G. on this one. There were many companies that used marbles as a giveaway. While I don't have this bag, there are many other legitimate bags that did advertising like this back in the 50's-60's time frame. Master Lubricants was a legitimate national company. Of course, there are a ton of fantasy bags doing this "same" type of marketing ploy to seem legit but they all use colorful marbles, not plain white ones like these. So, I would go with legit bag.

Dave did a good job with the "copying".

I agree on fake.

Agree with drizzle

Patterns are fun to find - a 'hearty' Rainbo.

Close but...

Yes - neat pattern.

Yup, nice one!

The are some real bags where companies did advertising like this. This could be one of those or a fantasy bag. Usually the marbles can place the time frame but the marbles here are hard to determine. When you get the bag, see if there is a vertical seam on the back of the plastic bag. If there is, it is legit.

And I would lean to Alley on the first two.

I don't think so - those little "breakouts" would not be in a cork.

Could be.

I'm thinking a messed up Vitro but...?

Yes, nice one.

Nice idea.

Not MK but not sure where I'd put it.

Cool Rainbo - love the colors.

Makes sense

Sounds right for Vitro. Looks like it would be in the "Lilac" family.

Agree with Vitro

Mummy is transparent purple with orange swirls. Orangutan is transparent orange with orange swirls. I'm just not coming up with a name.
