WHAT IS THIS THING? PAST-FUTURE

AK PURE LOVE PHOTOGRAPHY:

THIS ONE GOES OUT TO ALL THOSE WHO ARE YOUNG FROM THE PAST.LOL THIS IS MY SON IN THE MOUNTAIN SEEING A PAYPHONE FOR THE FIRST TIME (NO INTERNET SERVICE IN THIS SECTION OF ALASKA) HE WAS 14 AND ASKED ME MOM, WHAT IS THIS LOL I FELT OLD AND LAUGHED SO HARD WHILE ANSWERING THE QUESTION I NEVER THOUGHT I WOULD HAVE TO ANSWER LOL HE EXPLORED IT AND ACUTUALLY WAS SHOCKED THE PHONE WORKS. THE PHONE IS THERE FOR EMERGENCIES AND WHATNOTS IT IS FREE. BUT STILL A GREAT PAST/FUTURE PHOTO OPPORTUNITY TAKEN.
