Applied Illustration: Who are the target audience?

Upon my visit to the Yorkshire Air Museum I found that the majority of visitors were indeed the elderly. There were also the sort of characters you might expect to be enthusiasts in planes and making Airfix models.
However, there were many examples of younger couples and families also visiting the museum. The children were mostly primary school age, the older teens I saw were exclusively employees of the on-site cafe.

Thus; I intend to appeal to families and the elderly that have at least a passing interest in aviation.
I would suggest that these two demographics frequent the use of playing cards on holidays etc.

In terms of context, I would suggest playing cards could be sold in any historical museums, toyshops, bookshops and could obviously be distributed personally online.
