Upper Deck had a tendancy to do that. They would print the sets late in the year before the intended season, even releasing the set late the year before, or part one (series 1) of the set.
For many things the copyright date is for the initial copyright registration of that particular prpoperty. Many collectibles will have a very old copyright date for brand new items, A big Non-Sport cards copyright confusion due to this pratice is Topps "Planet of The Apes" cards. The original "Planet of The Apes" movie was released in 1968 the next year (in January I thijnk?) Topps released a 44 card set from the "Planet of The Apes" movie the cards have green backs (with black printing) and are copyright dated 1969. Then in 1975 Topps released a 66 card set of "Planet of The Apes" for the 1974 Television series. Those cards use the exact same front card design but the backs have puzzle backs and are copyrighted with the original 1967 copyright for the original movie properties. So over 95% of sellers on Ebay and elsewhere that are selling cards from the TV set mistittle their listings as being from 1967 or claiming they are from the movie when it is the TV show. Anoher example of the original copyright date being used for newer products is memorbilia (and cards) of Charles Schulz "Peanuts" characters. So many items with the bird Woodstock are copyrighted 1969 even if they were made in the 1980s.
