Can I ask how you know what is in where?
The box / tubes seem not to have any labels on them. Or are they all neatly turned away rom the front to maintain a clean frontage?
Any chance you can unify the longer tubes? They seem out of place next to the soldier-neat uniformity of the box tubes.
Each tube is labeled and I have an extensive database that tells me exactly where each poster is. I know what I spent on each poster, where I got it from, the name of the seller, when I got it, the condition of the poster, the cast, etc. I can find any poster in my collection within 2 minutes. Finding is easy, putting it all back to what I consider perfect alignment and stacking is very time consuming. I won't show you the inside of the drawers, but let's just say it's extremely tidy.
And no, I can't put the larger posters in the same tubes since I collect from all around the world and posters come in different sizes. 40x60in, 47x69in, banners, etc...
