Bob, you probably know this already.
If my memory serves me correct which I kind of doubt, there was a west coast find of E90-3 several years ago in which (believe it or not) there were several more Gandils compared to the other players. I'm sure those are neatly tucked away somewhere, but it gives one a bit of hope.
I had to way overpay for mine as it was essentially a set completer, but it's also one of my favorites.
Knowing the quality of cards that you collect and possess, I'm sure you'll find one soon. It does seem that E90-3 has dried up over the past several years. We use to have a few folks active with the set and a lot of discussion around it.
Remember that E90-3 Evers? Of course you do!
What the hell was I thinking??
