Very clever. It looks like it may be photoshop from the little artefacts but did you edit the images or actually make signs and take the photographs? Either way loved the post, very creative.
(You don't have to reveal your artistic secrets if you don't want to of course)
They are signs from an old steam train that I photographed then edited- unfortunately they didn't make Steem powered trains back then!
That's really cool. I know there's some dev with Eth at the moment looking at managing transactions for recharging electric cars. But a Steem powered Steam Engine/train would be amazing.
There are a lot of steam train enthusiasts out here, I think it would be easy to bring them over to the idea of Steem trains.
