The first world you'll travel to in Kingdom Hearts: Final Mix is Traverse Town, and there you can find an optional treasure hunt. Ten postcards lie around the town, and sending each through the mailbox in the First District will net you a reward, including healing items, stat boosts, and synthesis materials.
Unfortunately, you can't grab all of them until you've unlocked some later-game abilities and areas within the town (but you can grab some). If you want to get them all in one shot, wait until you've unlocked the Glide ability in Neverland before engaging in this perilous postcard pastime.
First Postcard
In the First District, activate the Blue Trinity in front of the item shop to be transported up a floor. It's inside the chest here.
Second Postcard
Once Cid has left the shop, he'll stand outside next to a counter you can jump over. On the other side is a safe in the corner. Interact with it.
Third Postcard
Behind a Moogle in the Synthesis Workshop, on the wall.
Fourth Postcard
On the roof of Cid's shop. Use the crate outside to climb on top of Geppetto's Workshop (the building with the green door) and glide over to the chest.
Fifth Postcard
Inside Geppetto's Workshop, on a shelf in the corner.
Sixth Postcard
Lock on to and attack the ceiling fan in the Item Shop to find this one. Don't ask how it got there.
Seventh Postcard
In the Second District near the entrance, there's a 'Boots & Shoes' shop. On its canopy sits a chest.
Eighth/Ninth Postcard
This one's a bit of a puzzle. In the Third District is an exposed wire sticking out of a pipe - to the left of the door to the First District. Shock it with Thunder. It won't be immediately clear what this does, but head inside the Second District Gizmo Shop to find it's now up and running.
On the upper platforms around the room are three buttons you can stand on. Activate them all and then interact with the clock below to get two postcards.
Tenth Postcard
From the Gizmo Shop roof, head through the rooftop entrance to the Third District.
You'll be on a little balcony, and tucked away in a corner next to the door is the final postcard.
