Help me if you can...

[Red Poppy]

Hi, I'm trying to track down a signed poster of one of Leonard's prints - they were sold at the opening of the Manchester exhibition a number of years back. I bought two but, in the meantime, gave them away as presents. I'm now trying to find one (ideally unframed) as a gift for a particular and special occasion. All (polite) suggestions, ideas or directions welcomed.
