A few days ago I released the first SBD back for my Steem Backed Dollars project. These bills are a fun way to represent Steem Backed Dollars using the minnow/dolphin/whale power representations we hear so much of on Steemit. I wanted the backs to be a little more geared towards the steam representations of Steem. Today I'm releasing 2 more backs.
These are also inspired by the history of steam power. I have another one just about finished and ideas for 3 or 4 more. Not sure what to put on the rest so if you have some ideas please reply with them. When I have a full set I will organize them in some way and put the appropriate denominations on them.
