From Lost Temple Traders:

"We’re all a little mad! Introducing the Zombie Hatter Mug designed for Lost Temple Traders by Bridget McCarty. This is a a timed pre-sale, and edition size will be set when orders close after 24 hours. The Zombie Hatter stands 6” tall.

Estimated Ship Date Q4 2022. Produced by Munktiki Imports."

The hat has "10/6" written on it. The 10/6 refers to the cost of a hat — 10 shillings and 6 pence, and later became the date and month to celebrate Mad Hatter Day.
