Notice that the flame marbles on the lower row of photos are showing their best faces. That had to be intentional. Yet, inexplicably, the two mint and most vibrant marbles (that also happen to be mimics of very desirable vintage ones) are hiding in the shadows.
If you knew nothing about marbles as this seller is claiming, wouldn't you put that most vibrantly colored one up front if you're already taking the time to carefully turn your flames to the audience?
Whatever is going on here, this is not a true "in the wild" vintage lot as no doubt the high bidders are assuming. That makes the seller's title all the more clever: 105 OLD MARBLES? IN A BOX WITH OLD MARBLE BAG? (That's called covering your behind.)
Then again, maybe I'm just trying to scare away other bidders so I can win the mint GOLDEN REBEL and SUPERMAN with a bunch of beat up vintage mibs to boot!
