Wow, this is so I impressive. Thank you @eliany for drawing my attention to this amazing project of @ubongudofot, it's really a well designed project.

For the Post quiz, since Steem is involved to the project, **i guess the colour of the shelves will be blue to blend with the already white wall and complete the steemit color, blue and white.

For the information on the sign post, I guess it would be Steem solar and electrical.

I'm inviting @alli001 @mhizta and @fortwis09 to make their suggestion.
