Interpretive hierarchy or signage viewing sequence is as follows:

1. Headings or images – seen at a distance that are appealing or attract interest
2. Images and illustrative materials – or maps and their legends which promote interest
3. Captions – which explain the images, illustrations and context
4. Sub-heading and labels – on diagrams and maps to be scanned for further information and finally
5. Body Text – if the materials above have held their attention or interest

So,  the all important content will only be looked at if you have a fantastic design and great images that initially attract the attention of visitors. Then of course you need the wonderful human stories interwoven with universal themes that everyone can relate to.
