One interesting feature of Megillas Esther is that Hashem’s name does not appear in the entire text. There are however a number of places that hint to Hashem’s name. The owner of the megillah pictured here had the sofer put three dots on top of every word that hints at Hashem’s name. The source for this is from the Chacham Tzvi. I will hopefully bring the exact place that this is brought down. Look three lines up from the bottom at the first four words and you will see the three dots.
