The Steam Winter Sale 2023 is expected to start on December 21. Valve has traditionally released a collection of cards.
You can already get one of the Steam Trading Cards for crafting a badge (from other cards); the collection consists of 11 cards. After the sale launches, you will be able to craft a special badge from them; also, during the sale, Valve will give a card for spending a certain amount of money.
