blank (unwritten) greeting

Exploration Stage: Christmas Headquarters
From: Miss Izzy
Description: I was so happy when I was appointed as Santa. Because there is so much room to try new ideas and innovations! My principle is "cut where you can cut. First of all, it's about manual labor. Can you pass me that blank postcard? I'll show you something good.
Completed: Nice postcards, right? But there are so many problems with postcards! Santa has to write each letter by hand, which is very time consuming. So we decided to replace them with versatile postcards that are pre-written, with only the name field left blank. See, I can write so much faster!
