Comments:
Very good condition given the age, braking by back-pedaling (aka coaster brake). All original except the 2 recent tires
Vintage Bikes: They are comfortable, simple and stylish. For short trips, occasional use, collectors, do-it-yourself projects, to decorate. Heavier, less performant and less reliable than modern bicycles. Fully functional, ready to ride, no warranty.
1 speed: for traveling short distances in a mostly flat neighbourhood. If you can walk there in 30 minutes, it should take around 6 minutes by bike. Not good for going up hills, even low grade climbs are hard. - Derailleur:
Tires 26 x 1 3/8: narrow tires with small thread, for paved road, very common on older bikes.
