"Definitely it is Wabanaki (Northeast Native American, encompassing MicMac, Penobscot and Passamaquoddy tribes) and I believe it is MicMac specifically, native to Canada's Atlantic Provinces and the Gaspé Peninsula of Quebec as well as the northeastern region of Maine. It is just gorgeously constructed, with fancy ash splint "porcupine" curls all around the sides of the basket and lid, and then this great splint flower spreading across the top, punctuated at the center with looped splint for a little handle. While I believe somewhat faded with age, the  exterior sides still show some of its original naturally dyed bright pink color--which is intensely vivid around the lip, on the underside of the lid, and on the interior walls."
