This is similar to IKEA’s Kallax bookshelf system, but this design has glass doors with a ‘window’ pattern (using frosted glass or sandblasted glass) to make it look like a building. The hard part is replicating the Daily Planet spinner on top.
With interior lights this would make for a neat display for your comics! Figures could also adorn the rooftop, as if they were patrolling the city.

I’d like modular shelving, so I could have a larger one for my hardcovers & oversize omnibi on the same case as the single issues. you could sell different toppers that way, too.
where can I get something like this tower?
I need this in my life. Please!
I want it! I need it!
