I have been working on older stamps from Columbia - ANTIOQUIA, BOLIVAR, BOYACA, CUNDINAMARCA, etc., and have a lot of questions. I am dumbfounded by how many of my questions can be answered by going through old Threads. E.g., I couldn't identify the stamps shown. philb could not identify them either on 07 Jan. 2017. meostamps and Nigelc identified them beautifully a day or two later. Incidentally, they are Ribon issues, or Cinderellas if you wish.
