Here is a set of 5 CAS-able abstract paint stroke style posters. The poster uses a mesh from the 2x1 posters from the Showtime EP. These are a clone of the mesh so they ARE base game compatible. Each painting has 3 recolorable channels and comes in the variations shown. They can be found under decor with all the other wall art. These posters will only set your sims back 50 simoleons.
Comes in both Sims3Pack and .package files.
Just some other variations I made in game.
