Crisp circa 1970 ballpoint signatures, “Peter Cetera,” “Robert Lamm,” “Walt Parazaider,” “Terry Kath,” “Chicago, Danny Seraphine,” “Lee Loughnane” and “James Pankow,” who adds a peace sign on an off-white 7 x 9.5 sheet. Affixed to a same-size sheet. In fine condition, with a trimmed right edge (affecting the last letter of the Seraphine signature), signatures slightly overlapping, and toning to edges. Pre-certified REAL.
