I went to one National..1990 or 1991 in Anaheim.

My business partner and I attended several major shows tho..Anaheim, L.A. San Diego, and several in Las Vegas.

We did a few shows at the Dunes, back in the day..they would have regular shows back then.

I have boxes and boxes of SCD's..1982 through the mid 1990's..very nostalgic looking back at them..and wishing I invested in 1952T Mantles, more older sets, or unopened material back then..for that type of material, prices are up to 20X now what they were then..
