Even though I live in Baltimore County, I've had occasion to receive both bills and paychecks from Baltimore City. The bills are for water & sewer services (which the city provides to surrounding counties) and the paychecks were for serving as chief election judge a year or so ago in the post-O'Malley special election for Mayor of Baltimore.
The printing on the paychecks said they came from the Mayor and the City Council.
The printing on the bills says they go to the City of Baltimore
As JFK said, "Victory has a thousand father, but defeat is an orphan."
UPDATE: Unfortunately I didn't take a picture of my Balto City paycheck. If anyone out there sends me a jpg of one, I'll post it here. Send it to baysense (at) comcast (dot) net. Please cover up the recipient and amount on the check.
