Below is a wand that was used on-screen in the scene in Professor Flitwick's class (where Hermione makes the feather float.)  As the camera changes to the overhead shot as Hermione makes the feather float, look at the very top row, the student at the far left end.  This may be that wand (there were about 4 of this style of wand used in this scene).  There's no way of knowing for sure if this is the wand in that shot, but the wand was definitely used in this scene by one of the students.  The easiest one of the 4 to spot in the classroom is the one just described. 

Below is a wand that was given to the attendees of the North American Premiere of Harry Potter and the Sorceror's Stone.  Note the "Harry Potter" logo burned into the handle.   The green wand box in this photo and the photo above came with the Premiere wand.  I only used it in the photo above to make the screen-used wand easier to see.

Below are eight different wand boxes that were used in the scene in Ollivander's wand shop when Harry went in to get his first wand.  Somewhere in the wall of wand boxes are these eight boxes.  The brown wand box at the lower right is more special than the others, because it is autographed by Maggie Smith (Professor McGonagall)!
