As a lot of you will now be aware American collector David recently passed away, I had the the pleasure of meeting and dealing with him on numerous occasions, he was a great guy and will be sadly missed, RIP and MTFBWY Dave .
What you have to remember is this was a 99p starting auction ,the bidding took it to £460 so there are at least 2 people out there that thought it was worth £450+
My advice would be.
If there's anything specific you want on the label to mention it,
If you have a variant item to mention that too,no one is infallible so it's better to give as much info as possible,helping them to get it right first time makes much more sense than having to send an item back...
