Nice video. Might have missed it but regarding the Heavy Metal cels, it might be mentioned that when the cels were originally sold they had the Heavy Metal "Embossed seal" which proved them to be authentic. There are many out there without the seal, does not mean they are fake, only that they were sold after the embosser tools broke and they were never replaced. But if they have the seal, they are prized a bit higher than the others.
