Hi OP, looks like you have a real rarity there 
Is this the cheque that you have in your possession? Just curious as this is the same image that appears in the original sales thread mentioned by Evilish

Any chance you could take a new image with today’s date on it as well as your username ?
Hope this isn’t too much hassle - but it would help your sale I’m sure
