Flag of the Wiltz Canton in Luxembourg, reconstructed. It is unknown if this flag is also used as the municipal flag of Wiltz now, since what is said to be the municipal flag — white with a coat of arms — cannot be seen on Google Maps flying in front of the town hall, instead this one, a red and yellow one flies.
Own work; reconstructed according to information from https://www.crwflags.com/FOTW/FLAGS/lu-wiltz.html#can. It can also be seen flying in front of the town hall of Wiltz. [1].
