Keep a small set of dated photographs that show the message, entrance and surrounding site from safe stationary viewpoints. Add a short note explaining what you want reviewed before the next campaign.
Use an overall view to identify the location and a closer view to show the artwork. Explain whether the question concerns the message, an entrance or a proposed change. Take photographs from a place you can safely and legitimately stand.
Label the context
Record the date and the viewpoint in plain language. A close-up of a balloon does not explain where visitors enter the property. Pair it with a wider image when the supplier needs to understand that relationship.
Turn the record into a review request
List the changes you are considering and ask the supplier which details they need to assess them. Arizona Balloon Company requests the location, dates, visibility goal and artwork when reviewing a display inquiry.
