WELCOME TO:

This letterbox hybrid cache has two stages, where at WP1 you will find the coordinates for the final location neatly hidden away at the phonebooth.
The final container is a regular sistema with room for swaps, holding a stamp and inkpad. Please do not remove either of these components.
Please do not spoil the cache in your log, either by text or photos.
GOOD LUCK, DON'T GIVE UP
Checker contains extra hints for GZ.
