5 Portland Street is the tax record for a two-family house located on Portland Street, Bridgton which Mortier D. Harris owned at the date of this survey, around 1938.

The card was later updated to reflect ownership by an unknown person (name obscured by label), and later Herbert Moulton.

The address given is the address at the time of the survey, and has probably changed since then. The card also references a deed dated 1934; this is not the date of the photograph.

The building was torn down in 1945, and the photograph has not been located.
