I enjoyed reading this mission...I love the artwork/photos...the styles is evocative and supports the theme of the adventure.
The writing is clear and concise, offering enough detail for a referee to decipher what's needed, but also allow plenty of room for interpretation.
The Sympathetic Objects premise is a cool idea and adds to the FIST world that fits well with the themes of the game (like Traits). There are some really fun examples (eg. The Good Camera, Grandma's Sweater, and The Easel). One question about tethering...do you imagine that the FIST team will know the procedure? or is this something they would have to discover in their search of the museum?
The opportunities to encounter the Unbound spaces (both with the SUPEREGO and on the existing area on the map) are intriguing and could generate some chaotic/fun aspects of this adventure.
Would love to run this with my group!
