A railway embankment...ummm, I hope you put up all the correct scaffolding, wore protective footwear along with Hi-Vis jacket and of course let's not forget the warning signs "Danger - enamelled sign collector at work"
Or maybe you just had common sense and took care, remember those days, pre HSE?
When I look back and think about how I retrieved some signs back in the 1970s. One in particular stands out. I cycled on my mums bike and unscrewed a mint Sweet Rosemary thermometer from a tobacconist that was right next door to a police station. 11 pm on Christmas Eve about 40 years ago in SE London !
