In 2009/2010, Ro Purser teamed up with Glass Eye Studio to design a group of marbles for the Cisco Systems Corporation. These marbles are being given away for 5 year, 10 year, 15 year (etc.) awards to employees of the company - yeah, I know, why couldn't I work for Cisco?!? Employees are able to select the style of marbles they want for certain year awards. This marble here is one of the super rare 20 year possibilities, VERY hard to find, and this is only the 1st one I've ever had for sale.
