Goldrush and Black Knight question

[M.J. Prior]

Victor:

> 1849? That makes him a little too old...

Nowadays, *every* 19th-century date makes $crooge too old 
to be still alive in the present, but *1849* would make 
him to be already over hundred years old at the time of 
his  first appearance in 1947! *gasps*

Still, it isn't just a random date, as 1849 is the year of 
the California Goldrush (the one in which Howard 
Rockerduck became rich (see Lo$4)), while $crooge earned 
his money in the Klondike Goldrush of 1898.

And now for something completely different:

In "The Black Knight GLORPS again!" $crooge lends his 
trophies to the Duckburg Museum for an exhibition. In one 
room the Goose Egg Nugget is on display, as well as 
various paintings by "$crooge's favourite artist". In the 
European version, these paintings seem to be a sort of 
pastiches on contemporary modern art, but in the American 
version these pastiches are replaced with pictures of *oil 
paintings by Carl Barks*!

See: http://www.don-mcduck.de/news.php#Juni-2006

Question to those who have read the American version: 
Which painting of Barks is the "stolen masterpiece"? (It 
turns up at the end of the story.)

Question #2: Who is the "collector in Baltimore"?

And are there fans who'd like to discuss "The Prisoner of 
White Agony Creek" now that it's released in Egmont 
countries? Did it turn out well?

Greetings,

Michiel Prior.
