Letters MY on bobble head Dobby doll

[Mary]

I can't figure it out and hopefully someone here can help me.

When the Chamber of Secrets DVD came out, Shopko stores offered a 
free bobble head Dobby doll with dvd purchase. The doll is a fun 
addition to my HP collection. 

The one thing I can't figure out is why the tea towel he is wearing 
has the letters "MY" on it. They are painted in white on the lower 
corner. I could understand if it said "MF" for Malfoy Family but what 
do you think MY stands for?

Thanks!
