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.
