More on these MOCs later.
The one on the rightmost screen is the classic space LEGO 6823 ( Surface Transport ). I have two of this. One was given to me when I was a child and now I’m playing with it with my own kiddo. The other one I recently acquired, unopened for 27 years before I grant it its freedom.
I’m not a ‘store them to increase their value’ type of human.
I’m more like if you buy it, you must a. play with it. b. use it and take photos and/or c. draw inspiration from it.
