Star Trek, The Next Generation: Technical Manual Easter Egg - Weird Map Details

I found this egg years ago before i even new what an easter egg was (not the ones made out of chocolate).
Ok. So just open the book to page 11 and you should have in front of you a cut-away side on view of the Enterprise 1701-D.
All the little internal details (the main bridge, warp core, even shuttles in the shuttle bay) are displaied as sillowettes. Ooo, Verry Pretty. but if you look closely you can see the sillowettes of some very odd things that dont belong on a starship in the 24th century. so far i've been able to find:
- What looks like a Porche in the main shuttle bay
- A rat
- A duck
- What looks like a symbol for a pedestrian crossing or ladies toilet
- A B52 Bomber or some such old aeroplane
I'm pretty sure that's it, but there might be more i haven't seen. Have fun!
