STOP #31: The Bellisseria and BBB Joint Birthday Celebrations at The Bellisseria Fairgrounds

So Bellisseria turns 6 and the Bellisseria Bureau Of Bureaucracy turns 5 and the BBB has taken over the Bellisseria Fairgrounds to celebrate.  There will be celerbations all week with DJs and live performers, and the BBB has created a retro design through which they are laying out their birthday bash.  There will be a number of stamps available, with, I believe, Lindens and Moles attending at certain points to have their passport stamps collected, and even the stamps have been designed with a retro feel.

 So, I decided to dust off my Bridgerton outfit and take a look.  They have a Victorian/Edwardian (I don't know which it is) style village downtown, and each of the Bellisseria Hot Spots has been represented in a retro way, such as The Gazette being contrived of vintage printing presses.  There's also a vintage amusement park with lots of rides.

I do know that they are touting some sort of mystery so I decided to hunt around and see if I could find it.  I don't if I managed to find the one they are talking about, but it is A mystery to solve.  I saw some postcard stands in one of the buildings, and they had the word Mystery on the placard above them, so I took a look and found "Beneath The Bunting and Underneath the Birthday Cake, Secrets Stir" ... A CLUE.

Now, listen, I'm not going to spoil the fun by providing spoilers, especially because I'm not really sure that what I found is what they were intending for the mystery.  But .... there are secret gifts to find, and they are very subtly hidden.  I managed to find quite a number of these (yes, I cheated, because I lost patience, and used an old hunt technique to unravel the mystery a little.)

NOTE:  One of the clues I found is in the picture to the right, but thats all I'll say!

One of the gifts is this cool top hat that you can size to fit your head.  Great work, BBB! and HAPPY BIRTHDAY!!!
