When putting your open class exhibit together look for opportunities to include "mini philatelic studies" where possible. These provide you as the exhibitor to show philatelic depth within the framework of your exhibit.
For example on page 6 or the example exhibit above there is a "mini study" on the UK Post an Go labels, showing the sparrow with normal and error printing label. Some other forms of mini study could explore perforations, paper differences and multiple printings of an issue, such as the Ireland blackbirds shown on page 7 of the exhibit above.

In an Open class exhibit you can have both philatelic and non-philatelic material included within the exhibit.
The general rule is that the non-philatelic material should not exceed 50% of the total exhibit. Care needs to be taken to ensure that the overall presentation of the exhibit is not unbalanced by the non-philatelic material that is used throughout.
All the elements of thematic class still apply to the creation of the exhibit. You need to have a plan, good story line and effective philatelic information appropriately placed.
