Just wondering...did Gladstone Gander get influenced by this, or something else? Or did Barks just think the whole idea of Gladstone on his own? I'm not insinuating plagiarism. After all, back in the sixties, there were two movies about the Hole-In-The-Wall gang out at the same time. Legit example of people thinking the same thing at the same time...I'm new to a LOT of things comics wise, and have the basics down, but don't know if the idea of an 'Unsinkable Funny Animal' goes back in the genre...
Carl Barks invented Gladstone Gander in late 1947 (he first appeared in the January 1948 issue of Walt Disney's Comics and Stories, as a rival of Donald for Daisy's affection. At first, Gladstone was a slightly dishonest con- man, he believed everything is fair in love and war. Soon, he started developing him, into a lazy lout, who cheated people for small sums, whenever he needed some money for something. Barks called him a "Conossieur of the fast buck". He once had false theatre tickets printed up, and sold them cheap to Donald, so Daisy would get angry with Donald when they were rejected at the theatre entrance, and Gladstone could move in and be her new beau. In spring 1951, Barks had an idea for an economics and morality tale built around Uncle Scrooge and his hoard of money. Donald and his nephews were working on Scrooge's farm. Scrooge was paying them almost "slave wages" to feed chickens, and dig furrows, harvest eggs, and the like, to teach them the virtues of hard work. He needed a catalyst to get Donald off the straight and narrow path, and to desert his post. He used the the lazy, friDonald's volous Gladstone as that agent. He gave Gladtone a new trait (or power) of unnatural, incredible good luck. Donald's exhausting work in the hot sun, and jealousy over Gladstone's life of freedom, taking advantage of his good luck giving him anything he wants at any time, leads him to join Gladstone in the life of leisure and adventure, "living off the land". The nephews remain working with Scrooge. Donald, hoping to benefit from Gladstone's luck, has him wish for a million Dollars (no small amount in early 1951). A weak cyclone spins directly over Scrooge's giant money crib (roughly the size of his money bin-but with only sides, but no top covering. The unprotected money is lifted into the air and blown all over the countryside. Everyone grabs lots of money, and decides to quit their jobs and go on an extended holiday/vacation like Donald seeks with Gladstone. Soon they all find that there is no food in the shops, and they are starving. They all come to Scrooge's farm, and his money bin fills up once more, and he earns even more.
Barks had now opened the jinn's bottle. He had now given Gladstone a highly-memorable trait, which might be somewhat difficult to remove, IF he'd want to use Gladstone in the future. But he DID want to use Gladston'e super luck in a few more stories, which, having done so, definitely cemented that trait into Gladstone's character.
Irv Spector's "Lucky Duck" was issued in early 1953, more than 2 years later. If either of them were inspired by the other's work, it would have been Spector borrowing the idea from Barks. But he changed it quite a bit. Gladstone is a rival for Donald, and a model for him of how NOT to be a decent human being. He is lazy, selfish, arrogant, and cares nothing for others, and has no real friends. He is a warning to Donald to not value material things, as happiness comes from being able to look at ones self in a mirror, and like what he/she sees.
Spector's "Lucky Duck" pits two neurotic souls competing with each other to get the best of the other. The egotistical Lucky Duck, who always ends up on top, wants Rocky Rabbit to try to trick him, and apparently that amusement is the main reason for his existence. Rocky Rabbit, who desires to show his cleverness, lives for tricking Lucky, and getting the best of him. This scenario is different enough from Barks' use of Gladstone Gander, to make it clear that he only borrowed Barks' idea of an unbelievably lucky person, OR, possibly, came up with that idea on his own.
In any case, as stated above by several posters, Lucky Duck's weak or completely missing storylines, hurt its potential entertainment value. As artwork is much more important to me in my enjoyment of comic books, I still enjoy "Lucky Duck"; but, of course, I enjoy Barks' comic book work thousands of times more.
