Bobby’s poem, Sunday Bonnet, is featured in the 33rd issue of The Floating Bear which he wrote in the Winter of 1966.
The Floating Bear was published nearly every month and distributed by mailing list only.
It was never sold and supported by the editors and donations. This mimeographed newsletter would reach a few hundred people every few weeks.
Diane di Prima published the entirety of The Floating Bear newsletter in one volume in 1973 titled, The Floating Bear: A Newsletter : Numbers 1-37, 1961-1969.
