Revisit in cache "OTTT #4 – Museum of Modern Art" on 01/28/2023 to check for trackables. None found, which means that TB2317G FTF Christmas Geocoin was not present. (No log at the cache page. as I have visited the cache several times since September 2008.)
Coin owner and cache owner, please consider to move the traveller to Unknown Location (Mark Item Missing) if it doesn't show up soon.
