Wasn't aware that some of the MURRAY Olympic and/or Seven-11 decaled bikes were made by Tom Kellogg in addition to Ben Serotta. Aware that some Seven-11 riders used non-Serotta frames with Murray decals also, but this is the first Kellogg built frame I heard of.
One is currently listed for sale on eBay and can be viewed via the following auction address (or item #290422301033):
