An associate of mine is trying to locate a graphic that was posted some time back. Thinks it was mentioned or posted to the list serve but not positive. It's a horizontal timeline [or more of a horizontal, backward running family tree] that detailed the history of merging record labels of the 78 r. p. m. era. Sort of a who bought who since the late 1800s or early 1900s with lots of pretty colored lines. Holler if you remember something like this.
