At the Seriernas värld exhibition were three Mickey Mouse strips on display.
(Click to enlarge.)
I've seen them exhibited before and always labeled as Floyd Gottfredson art.
If you know your Gottfredson art and how his style developed over the years it's obvious that the strips are by someone else. Notice how the copyright year has been removed to make identification harder. They were probably sold as Gottfredson dailies by someone who knew they weren't. Here are some close ups:
The first time I saw these strips I thought they were made by an assistant, toward the end of Gottfredson's run. But after seeing the original below for sale on eBay I'm quite sure wich strip we are dealing with...
"Mickey Mouse and his friends" was produced during the 50's and 60's and the main difference between this strip and the regular MM strip was that it always were a pantomime strip. (Just like the three strips at the exhibition.)
Checking inducks and comparing artwork I'd say the strips are by Julius Svendsen, not Gottfredson.
Anyone who disagree?
