Christmas Background for 15-30 rubles: D

Project Zomboid card

There is one foil card, at the market price a month ago it cost 700r. But of course I already realized that no one would buy it.
From a regularly purchased product, there is a smiley in the shape of the Moon for 50r. with more than a background for about 80 and a poop-shaped smiley for 60 rubles, which, as it were, symbolizes these market prices in general.

Card "Alpenjäger" from the game verdun and it is sold from 11.50 rubles :)
