Delighted to see at the post office -- and purchase -- a set of first-class postage stamps featuring first-class 20th-century American poets: Brodsky, Brooks, Williams, Hayden, Plath, Bishop, Stevens, Levertov, Cummings and Roethke. Seems like some of them were here just yesterday -- like Denise Levertov -- and I'd rather give that space to Howard Nemerov, whose poetry I like better -- but it's a fine gallery to start with. It's a sheet of 20 but features only 10 poets. Here's the Sylvia Plath stamp we have all been waiting for. Read or re-read the early works of Gwendolyn Brooks: wonderfully gymnastic, mind-bendingly original formal poetry. Of this entire group Brooks is the most underrated.
