Determined Productions 1985 Snoopy phone. Determined Productions designed and produced products for the Charlie Brown line. This Snoopy phone features a touch key pad on the base. Snoopy, Charlie Brown's best friend, lays on his back. He has a red cord which connects to the wall. Snoopy is in working condition.
