At various times during its publication history, Marvel Age magazine ran a one-month calendar on the back cover, noting the birthdays of Marvel staff and including comedic bits. The calendar for December 1985 had room for a cheerful illustration wishing everyone a Happy New Year!!
Comic books and other magazines often display a cover date set a few months in the future of the release date. In this case, that December 1985 calendar appeared on the back of Marvel Age #35 (cover date March 1986).
This makes Valkyrie's appearance in the New Year's scene especially noteworthy, as the future of the character was indeterminate as of New Defenders #152 (cover date February 1986). Given the character's longstanding history with the Defenders, I'm glad Marvel's creative team featured her in the end-of-the-year celebration.
