BTW I know Casandra personally I had her do several appearances for me in the past... if you ever want your backglass signed here is where you go
There is a tradeshow in LA called Monsterpalooza its every April I think and another in October. She's always there... I've been several times and seen people walking around with Elvira translites.
They have one coming up in September it doesn't say she's going to be there but she always ends up with a table. http://www.monsterpalooza.com/fall/
