I'm not sure who made these or exactly what years.  The first appears to have been made somewhere between 1965 and 1969.  Harry became the official mascot in 1965.   The second was made for the 1972 Orange Bowl, note the opposing NU and Alabama helmets on the sides.  The third version (white) features Herbie, so was made after 1973 when he became the official mascot after Coach Tom Osborne took the helm.  Click the third for a larger view, with a second view next to it.

     These beverage mugs come apart for cleaning.  The base is a tee which comes off when you twist it 1/4 turn.  Inside the mug is a clear plastic liner which you can either pour your beverage into, or place a 12 oz. can directly inside the liner.  It is hard to see, but the label on the bottom of the white version simply says "NEBRASKA".

     Thanks to Bob Ihrig  for the Harry scan, and Dave of Omaha for the '72 Orange Bowl photo.  The Herbie stein is part of my collection. 

1970 Old Harry Husker Plastic Stein

Brian Beverland submitted this photo of a very nice plastic mug or stein commemorating the 1970 National Championship. It is interesting since it goes back in time a little, showing a previous caricature of Harry Husker from the 1950s.

1970s or 1980s Lidded Football Stein

     Not sure of the exact timeframe that this gem was first put out, but it is a really nice hard plastic lidded stein similar in design to a few of the plastic steins from the 1970s and early 1980s.  It stands about  8" tall.  

Thanks to Chad Maun for the photos.

1994 National Champs Lidded Stein

     Another nice lidded football stein, this one commemorating the 1994 National Championship with the win over Miami in the 1995 Orange Bowl.

     This is a unique megaphone that is actually a mug. It has a picture of Herbie and it is a mug as you take the lid off but you can also take the bottom off and it turns into a megaphone. This one is signed by players of the 1989 Cornhusker football team. Also listed with the Megaphones.

Thanks to Arnold Remington for the photo and info!
