Another non-railroading book, but one which readers of this Web site
will enjoy. Primarily this is a photo book, with an older Baltimore
area photo presented on the left side page, with its present-day
counterpart on the right.
A drawback: often the two photos are not matched up very well,
sometimes they show different angles, sometimes the present-day
photo cuts off the top of buildings shown in the old photo, etc.
An index would be nice too. Despite this, still intriguing.
