We started producing trading cards for high school and other amateur athletes. Students found they work much like senior pictures, but have a memorabilia quality to them.
These are examples of simple template design cards.
To keep the cost down for everyone, we automated much of the process. The athlete, parent or boosters would fill out easy to follow web forms with their stats. These could then be auto-placed into InDesign. Only custom editing of the photos is required. Most of the time that is minimal and can be handled with scripts as well.
