I remember someone saying that on your first mission to the sedgewick, you can walk past a room and see the Spiderwitch logo on the door. What part of the Sedgewick can you see this? And what room number was it? Is it when you are upstairs with Ray and Peter or after you go upstairs with Egon chasing the Fisherman with the hallways all flooded?

That and mainly I can't remember what the Room number was again.

room 1221
but i dunno which part of the level it is

This is funny, i went by the room (by the way, it was right when you find the first artifact) and I didn't see a Spider logo or anything on the door or door handle. Wasn't there supposed to be something here that you could see before you come back in the Return to the Sedgewick mission?

There is, but it only shows up when you're wearing the Paragoggles.

Also it's during the “chasing Slimer in the hallways” bit of the game.
