I do not have a picture of series 50, nor do I know what set series 50 is. If you find out, please let me know! I have a feeling it was the Bohemian set that was re-released, but I am not positive because I haven't seen it.
Series 36 contains a total of 19 stamp sets, which is the first and only set that had an odd number released. This photo also contains the 2 acrylic blocks that were released with this series.
Series 20 is an adorable Halloween and Thanksgiving set. There are a total of 19 stamp sets, which is the first set with an odd number. Also pictured are the 2 acrylic block sets that were sold with this series.
Series 14 contains a total of 16 stamp sets. There were an additional 8 images released, but I have yet to find anyone who actually purchased them. I believe that the release from Hampton Arts was a little pre-mature and the additional 8 stamp sets were never produced.
This is the only photo that I found of series 3. It was mislabeled and states series 2, but I haven't been able to erase that part yet. It has been confirmed by looking at the back of the packets. There are a total of 16 stamp sets in this series.
