Your double happiness picture is a printed calendar picture. Because it is printed on rice paper, it looks like a painting with a seal engraved on it: Taizi of Donghai. A complete set of 6 calendars, namely: Double Happiness, Autumn Leaves, Plum Blossoms, Songhe, Running Horse and Double Auspicious Size, 67X28CM(3) and 67X38CM(2).
There is also a double happiness picture of the same length, width and size in the last paragraph: Xu, Shi Zhizhen are in obscurity.
I hope I can help you.
