Anthracite.com, early 20th century edition

You can order your coal by telephone! Imagine: no more dispatching orphans down to the coal yards, crying for anthracite and striking a less than advantageous bargain with the local collier. No more waiting to learn of the bargain while the orphan is distracted by games of pitch-penny or roving tobacco gangs. You simply pick up the telephonic instrument, scream the complicated three-digit calling number at the girl, and in minutes you’re connected with the main office. Will the wonders of this new century never cease?

Yes, there is an Anthracite.com. They don’t give out their phone number.
