There are those who don't know what they're selling, and those who know what they're selling and hope people don't know what they're buying ... I'm not sure which this person is.

I did an EBay search for Robertson clan items, and one of the results was this "Robertson clan badge" .

I know it's not Robertson, but I've seen it associated with another clan. A quick search of the internet resulted in the Campbells.

Any Campbells out there interested in taking advantage of this person? ;-)
Or Robertsons who want to correct the seller?
