Two make one brand new would be about £20.00 as a one-off..... The fact that it's old and tatty would make it cheaper.... The fact that it's a bit historical and some nutcase with more money than sense will probably want it means it may be worth more......
All things considered, I reckon your in the £10.00 region...
Coming next on dickinsons real deal.... One of Paddy Hopkirks socks........
its something someone wouldnt make tho its something someone has from the day, otherwise everyone could go and make a copy of a famous painting and that would decrease the value of an origional then yeh?
Tends to work the other way ..... The more copies and replicas you have of something, the more notorious the original becomes, and it's value increases.
But let's face it.... It ain't no Degas.....it's an old sign...... But someone somewhere will want it with a passion.
