Hello. Saw a 2 gallon royalene motor oil can...got a oil rig type of graphic really pretty cool can...but thing is never found any info anywhere about it?. Are they rare?. And if so. What's the value on something like that. I don't have a picture. But any info in general about the company would be good. And if the can was even a 5 out of 10. What the estimated value. Thanks.
