i dont know about underwear no such thing out hear. But I think the logo was changed in mid 80s. I know I still have a few of the old logo signs in the shop. The stihl rep. casme in 1 day & said I have to take them down. & remove my yellow page adds with that logo. Well I did not. Then he came back in a yr, or so & told me to clean up the floor. Always have 30 to 40 stihls on it for repairs. I told him if he wanted it cleaned up to grab a broom.Stihl has changed a bunch in the years. I guess its a money thing.(darn eager beavers)
Just don't you worry about it right now. hey do you know a man named Carrol up there in them parts? World Champion Chainsaw Carver some years ago or something. Was talking about the Louisville show. Anyway, you don't need to worry about them smilies or something. Concentrate on not getting sick on them KY whiskies.
