33 Venezuela used postage revenue and school stamps, mostly 1890’s to 1910’s. I am not a stamp collector, but the left 2 stamps in the second row seem to be from 1882; the next one, blue, seems to be 1914; the Escuelas" revenue stamp at the right end of the row seems to be 1882. The "Instruccion" Bolivar revenue stamps in row 3 seen to be from around 1904. The "Instruccion" Bolivar revenue stamps in row 4 seem to be from between 1893 - 1906. The Bolivar mail stamps in row 5 seem to be from 1899. The ones below that seem to be from the 1970’s and 1980’s. Ungraded and uncertified. (#311)
