In this article, the 2-variable general polynomials are taken as base with Peters
polynomials to introduce a family of 2-variable Peters mixed type polynomials.
These polynomials are framed within the context of monomiality principle and their
properties are established. Certain summation formulae for these polynomials are also
derived. Examples of some members belonging to this family are considered and numbers
related to some mixed special polynomials are also explored.
