Is this a tarantula?

I will attach the picture so that the non-spider people won't have to deal with it.
This spider was in our office just now. A co-worker caught it in a large manilla envelope and took it outside.

I looked online and I believe it is in fact a tarantula. It was so neat to see it in person.
Oh, the actual size of it was about 2 1/2 to 3 inches in diameter.
