I have several OA questions:
1. Why are the corners clipped on some pieces - I guess this is more prevalent on bronze age pieces. Does this affect the value of the piece?
2. What do I need to know about the material/media that the OA was done with and on? Does any certain type of media (paper/ink/pen combination) tarnish with age?
3. What terminology should I look out for that isn't obvious - how do I know the OA was a genuine published piece and not some reproduction?
4. Are there any detracting factors that collectors typically look out for if they are unsure about a buying piece. Sort of like how some comic book collectors may shy away from a book with brittle or tan pages, or some other aesthetic factor.
Commission questions:
5. What is the basic procedure for obtaining a commission, and what's an approximate average cost for this (depending on different levels of artist skill/popularity) - do artists just tell you when you ask?
6. Are commissions usually mailed to you when they are complete, or does the artist finish it before the end of a multi-day con?
7. Do artists typically allow you to tell them what to do/design?
8. Is there anything that I should avoid saying or doing that would offend an artist - any weird stories about this?
Thanks for the help!
