Posted on 14 October 2014 in Portland, Oregon, this extremely valuable cover shows numerous examples of the ultra rare Inverted Kitty error. Only a handful of sheets of the Inverted Kitty were distributed, most of which were destroyed once the error was discovered. It seems that "Friends of 4449" must have purchased one of the few sheets that slipped through the cracks, and made liberal use of these stamps on this now highly desirable cover.
The Friends of 4449 is a non-profit organization that is dedicated to the preservation of locomotive SP4449:
SP 4449 was built in 1941 as a GS-4 “Northern” type locomotive. A 4-8-4 wheel arrangement. Retired to static display at Oaks Park in 1958, most thought SP 4449 would never run again.
In 1974, she was selected to pull the American Freedom Train throughout the United States, and was subsequently rebuilt. SP 4449 ran for three years to the delight of over 30 million people. She is arguably one of the most beautiful locomotives ever built.
