This card originates from Canada, but Pow Wow event is practised throughout the North America. It is a gathering of native people of the continent, where also non-native people participate in celebration of American Indian culture. It usually involves a dancing competition and ranges from one day to a week in length.
Such a happy, colourful card! I am certain participating or just watching one of these events would be a tremendous joy :) many thanks to incrou7 for this private swap :)
