Don't use the apostrophe (as in the thread title) in Tetons.
As others pointed out, don't include "Grand."
Including that giant text on the image is more in line with producing a poster than a fine art print - is that what you want? If not, simply sign, title, and perhaps number the print in the margin below the image and mount in a window mat that is larger than the image area by .5 to 1 inch so that the signing shows.
Someone was very emphatic about not using a white mat. That is a true outlier notion, since the standard, traditional method of mounting is to use a white mat. There are other options, but most people feel that mats in colors or black are more likely to over power the print itself.
Regarding prints versus online presentation - and not unrelated to the white mat question... prints that look fine on the screen, where the light "glows" though the monitor, can end up looking too dark as prints, where the light comes from "on top of" the print. One way to ensure that you don't get caught in this trap is to work on the screen with a white background. I know that black backgrounds look great, and that some recommend neutral 18% gray, but both of these can trick you into thinking that your image will make a fine print when it is actually too dark. The truth is that much of the work done to prepare a photograph for print is about adding light to the image - working to optimize highlight levels, doing various things with curves, and so forth. You are most likely to end up with a beautiful, light-filled print if you work against a white background on the screen.
If you are not familiar with this stuff, some things to consider:
1. If you go to a frame shop that knows about mounting photographs, they can give you some pointers and ideas that may help. They can also help you with frames. There are all kinds of ideas about frames. Many photographers prefer simply, narrow metal frames that do not overpower the print. I like the black Nielsen metal frames, though the silver version are also a nice alternative.
2. I assume you are sending your print out to a printing service. They may also be able to help you with these decisions.
3. If you have not done so, visit some shows or galleries that include photographs of the sort you do and see what kinds of presentations are used and which appeal to you.
4. Some interesting alternative presentations also are available including canvas printing, mounting directly to metal and plastic materials, and so forth.
5. I would avoid printing anything on the paper other than the print itself in most cases - no printed borders, text, etc. (There are exceptions, but they usually are not for large wall-mounted photographic prints.)
