Holiday Wreath Forever First Class Postage Stamps

Wreaths, four of them, issued in 2019 and drawn from early American decorating traditions but rendered cleanly enough to sit on a modern envelope. A wreath is one of the few holiday images that predates the holiday it now belongs to - evergreen rings were winter markers long before they were Christmas ones - which is part of why they read as warm rather than as religious.

That makes this the practical choice for a mixed card list. A wreath on the envelope says December without saying anything about what the recipient believes, which is the position most businesses and most extended families are in. Booklets of 20, four designs repeating through the book. Households working a full card list usually buy several. Anything left in January is not wasted - Forever value holds, so the leftovers mail ordinary letters at the current rate.
