I have no ideal how long Hunt's Manwich has been around however it seems forever as we have always had a can or town in the pantry. It is a great items to prepare quickly especially when kids drop in and want more than just a potato chip snack. Easy to prepare and the kids all seem to like it. It is also very inexpensive compared to heading out to a hamburger place to get burger for four of five kids. Guess we will continue top keep a  could of cans on hand at all times. Great item.
