This one has nagged me for a long time.  It's been in my possession since early to mid 90s, but don't remember exactly what year or how I got it.  I spent 20 years thinking it was real until I really got into the hobby.  I tend to think not his signature, but have seen a couple older signatures of his that look somewhat similar.  What are your thoughts?

Mine...
