I don't yet have the capacity to list specific objects other than the ones that you'll see offered as bonus rewards here. Your best bet is to back the project, keep an eye on the updates, and comment on any update that happens to feature something you're specifically interested in or have information about.
Some folks will no doubt find extra special treasure in their boxes – and other unwieldy items will be made available through some special giveaway events. But first we've got to get the project funded, ideally to the third stretch goal. If that happens, I'll have more breathing room and bandwidth to try to get specific items matched.
I'm trying to do my best to honor my dad's wishes & legacy with the available time and energy that I have. Thanks for your patience & support!
