The nice thing about museums
Not just vacuum museums, but any museum; you get to see different things from the perspective of the curator or other visionary that designed the format.
One can go into the Guggenheim and see a different perspective than if you visited the Museum of Modern Art. Both could be displaying the exact same painting and you would see it differently.
None of the museums are arrogant enough to claim to be the only one, or the only one with the correct perspective; they are allowing the visitor/viewer to make those determinations for themselves. A museum operates like a teacher on display, it is living and changing. Some are interactive, some are roped off, some are historically accurate, some operate on revisionist history; all serve their purpose in the process of educating and preserving.
I know that there are also some virtual museums as well that serves vacuum cleaners and their history. Maybe some members can post those links as well. As collectors and aficionados it is nice to have a wide variety of information available to digest and allow us to be more informed.
A museum that displays art with the intent of selling that art or other pieces is actually called a gallery, one can see a conflict of interest if they display a Rembrandt, but their sole purpose is to sell Monet.
