Very interesting and rare calling card/business card for Victor A. Nicholson, a teacher of Piano, Organ and Harmony.  He was also the Organist at St. Paul's Church.  Below is some information I found while researching his name on the internet:

Musical Career & St. Paul's Church
Private Teaching & Residence
  • Studio Location: Outside of his Sunday service commitments, Victor was a respected local instructor of the "piano, organ, and harmony". 
  • Local Ties: His name appears periodically in neighboring New York and Massachusetts social columns. For example, he traveled out of state to visit his family members, including his brothers Harold and George Nicholson. 
Because he operated his studio in the late 1800s and early 1900s, his primary footprints remain in physical town registries and scanned newspaper microfilms.
