Do most "Con Sketches" happen before hand? Does an artist get contacted before a con for a commission, then brings it to the Con for the buyer to pick up by/with a CGC Witness. After reading some posts this seems to happen quite a bit. Is this the perferred way for most artists and/or just a way to make things easier to set up for all parties involved.
Personally, I prefer this as I like to plan ahead and definitely know what I am getting at the show. This way I know what I can get during the show. I have been trying to find time to get ready for Boston; I have contacted quite a few artists, many of which got right back to me. I currently have 3 artists working on 5 covers.
If you go this route, definitely find out when you need to get the books to them by. I had to order more blanks and the 3 I have, I guess, contracted with gave me definitive dates to work with.
I like this way as you can see what kind of sketches the particular artist turns out and it may help in narrowing your commission request. Say an artist turns out awesome masked characters; you want a female character. If you try to get it done prior, you can at least have some sort of expectation.
Also, some artists require a paypal deposit or payment in full and others prefer cash at the show so know that some really wont communicate about the particulars until they know you are serious by sending them the money.
Best of luck to you! This is my first year trying to go all out with sketches and I hope to have a great turnout at Boston!
