In this post we have a US 290 10 cent stamp Hardships of Emigration from the Trans-Mississippi Expo Issue. this It is used as you'll notice the cancellation on it. Perhaps not the best looking cancellation but these generally don't. As far as the centering, it appears to be very good. The theme of this stamp is of a family emigrating to the Western United State in a covered wagon and in this case dealing with problem with one of their horses.
