In Memorium

Finney & Son mausoleums & monuments. 1850.
Philadelphia, PA, USA

This building still stands, barely, on North 12th (?) Street, just north of Spring Garden Street, in Philadelphia, PA..  I wonder what's inside; is there anything remaining of the original business in the basement, etc.?  What happened to the business, the owners, etc.?
