Each summer the MSCVB puts out a series of 4 black and white ads, each covering a different aspect of the Mat-Su Borough (glacier hikes, fishing, canoeing/boating, RVing, etc). This year we changed it up a bit by making the ads look like WPA posters from the 1930's, featuring illustrations by me. :D
We've since carried the WPA flavor over to the 2008 Mat-Su Visitor Guide. The guide breaks the Mat-Su Borough into 5 regions and each region gets its own WPA-style postage stamp. The above image is actually for the "Off the Beaten Path" region, which is everything in the borough that is not road-accessible, but I thought the sky was a good place for text and so dressed it up as a Denali poster just for fun.
The background is closely based on an actual WPA poster for Montana or something - the mountains came pre-resembling Denali so I borrowed their design, though drew it from scratch and did my own color theme. The Cessna 180 is from a photo I took - the colors are totally changed (the original plane was white with brown).
I'll have to upload those ads and the other stamps sometime.
