Coo-Coo question (Barks)

[Daniel van Eijmeren]

In private, I've been asked the following question:

"I have an original copy of " Coo-Coo " and according to the 
Bruce Hamilton website there is only 1 known copy in the world."

Does someone know where exactly this information by Bruce Hamilton 
can be found? Or can someone quote the information? I couldn't find 
it at http://www.brucehamilton.com.

What I would like to know is:

- Does the information mean that only one issue number exists? 
(In other words, there's no "Coo-Coo No. 2"?)

- Does the information mean that there's only one copy of "Coo-Coo 
No. 1", because ALL other copies of "Coo-Coo No. 1" got lost during 
the years?

- Does the information mean both? (Only one issue number exists, 
which also is the ONLY surviving copy, because ALL other copies 
got lost during the years?)

I find the first meaning most likely, but I would like to know for 
sure.
