how would I remove an object from one slide only & change master s

[Riki]

i have a master which I using for most of the presentation. At the start of
the presentation I want the first 2 slide to be different from the master
slide, how would do this?

It sounds to me like you've set up a slide master. You can also set up a
"title" master (in View > Slide Master) with a different look. When in Slide
Master mode, select Insert > New Title Master.

Then in normal mode, select Format > Slide Layout. The black and white
thumbnails at the right give you layout options. Go to the slide that you
want in this new layout. Then in the thumbnails at the right, click the drop
down menu of the thumbanil in the upper left corner. Select Apply to
selection. Repeat for the second slide that you want changed.

Let me know if this works.
