Fire, I have been doing some more research and this is where I am. The OP is not a Woodstock Lawn Chair marble. The Woodstock appears to be a multicolored swirl that had some metallicI that ultimately became known as Woodstock. They were red white and green and 5/8 and 3/4, translucent or opaque and look nothing like the other Lawn Chairs/Metalics. Kinda confusing on the name then. Yours looks to be a cool 1" Metalics run various sizes run and marketed. There was a lot of information on this and after some digging it appears that the ones in my collection are also from the same Metallics! 🫢 What hope did I have of thinking they would unknowingly be from the original run? LOL!!!! They didn't cost much and well I let my excitement get the best of me. There are worse things, they're still cool!!
