Given a real projective plane S embedded in a 4？manifold X4 with Euler number 2
or ？？2, the Price twist is a surgery operation on .S/ yielding (up to) three different 4？manifolds: X4 , S.X4/ and ？S.X4/. This is of particular interest when X4 D S4 ,as then ？S.X4/ is a homotopy 4？sphere which is not obviously diffeomorphic
to S4 . Here we show how to produce a trisection deion of each Price twist on S X4 by producing a relative trisection of X4 n .S/. Moreover, we show how to produce a trisection deion of general surface complements in 4？manifolds.
