I found this retrospective from Rare Gamer where they reviewed Rare’s annual Christmas cards from 1995–2021:
There’s a particularly festive tradition that’s recognized each holiday season at Twycross when the Rare staff will get together and create Christmas Cards themed around both current releases and titles yet to come.
Some designs are shared internally, whereas others have been posted through Rare’s social channels online and, if you’re especially lucky, mailed through personally as a gesture of thanks and goodwill.
Looking through them, it’s like a 90s gaming time capsule with all the love for Donkey Kong, Banjo Kazooie, and Conker.
