BRST invariant tadpole operator in the bosonic string

Using a BRST invariant three-reggeon vertex we construct an explicit expression for the BRST invariant planar tadpole operator for the bosonic string. Joined to an ( N+1)-reggeon vertex it yields the correct expression for the one-loop N-tachyon amplitude.
