These North Korean postcards are 3D, lenticular printing covered in ridged plastic. On the reverse, in Korean and English, they identify the statue and the location (Pyongyang); they are not formatted in postcard style, though they can be used as postcards and were sold that way.  Two are unused (Grades: 1, $19) and the third was mailed from Malaysia (not North Korea/DPRK!!) in 1991, with two Malaysian stamps and blue Mel Udara label affixed (Grade: 4, $6).
