Dirty windows

This is a window in the workshop attached to the tiny office I work a couple of days a week. Scot is my oldest brother. 30th October 1976 he wrote his name on this dirty internal window and to this day it hasn't been cleaned off. My family took over this buiding in February 1970 so the dirt had no doubt been building up since then. There are four windows in this window frame. One of them is now smashed so there was no space for me to add my name. I did shove a sticker on the wooden frame on the 29th March 1983 and it is still there.
