I had a seasonal beard for 25 years...grew it in the autumn, shaved it off in the spring. I worked OK for me; saved wearing a scarf in the winter. As the years passed the inevitable flecks of grey began to take over and I gave up the practice in the early '90s.
I did grow one as a period "fancy dress" feature when we drove our old banger to the Le Mans Classic a few years back. If you wanted into "The Paddock" you have to dress in the period style of the car you drove.
The beard and tash lasted until the similarity between me and Col. Sanders was noted.
Man from del Monte? /Our Man in Havana?/Howard Hughes? A life time of potential roles there slowy,dont limit yourself to Satan's Chicken Frier
The first name to spring to my diseased mind was Leon Redbone. Looking like Leon Redbone would be pretty damn cool, I reckon.
