Went through your updated pics and, not that I wasn't seriously impressed before, I have to say that my jaw hit the floor... again! Two weeks ago I went through and re-boxed my own collection since the containers were collapsing in on themselves due to the weight of the stack. I have no room currently to display them so they are in storage but now they are all in durable, weather/weight resistant tubs aside from the small selection I have inside and my Prime collection which is stored in a separate storage spot (and after seeing Autobot Joes Prime collection I am suffering a major case of "Big Bot" envy).
I can't wait for the day when I can pull my collection out and photograph/organize it the way you have with yours. That is truly an inspirational collection you have there.
