Your question begs a question. I'm wondering why you printed 50 giclees of the same image. The primary appeal the POD (print-on-demand) process is avoiding a big initial investment in a long print run. The horse is out of the barn on this and as such it's too late to shut the door, but please consider it for the future. If your giclee printer convinced you this was a good idea, I'd consider other options for future work.

Your question reads as if you are hoping to find someone to purchase the remaining 45 pieces in one transaction. If this is the case, it's wishful thinking on your part, particularly if you expect to keystone (A keystone markup is a markup that is equal to the cost of the merchandise, essentially taking the cost of an item and doubling it to determine the next level, wholesale or retail, price.) the images. Established artists with loyal collectors and a network of galleries would not expect to be able to sell 45 prints to one person or company, unless it was a wholesaler who had a market for a certain look. As it is, most established artists have to work pretty hard to sell 45 prints of any image.

If you are unknown without a following and have a single image, as your question implies, then you need to pull back from trying to think about selling a bunch at one time to selling one at a time. This will require some time, effort and expense from you. Typically, galleries and collectors want to see multiple images from an artist. It allows them to see a range of the artist's creativity and assures them the artist is committed to making more art should their interest be piqued enough to purchase the first image. This is especially true if the work has a decorative quality to it.

To sell them locally one-by-one, you will need them to be framed, or if on canvas, stretched as a gallery wrap or image wrap. The difference is the former has the whole image showing with the sides painted a complemetary color. The latter wraps part of the image around the sides. In other words, they need to be ready to be hung as finished pieces. 

I would start selling to family, friends, neighbors and so on. If you can find some locally owned coffee shops and gift shops, or artist consignment shops, those are all good places to get the pieces shown and eventually sold. You might talk with local picture framers to ask if they would hang the piece for you on consignment. If you are already giving them framing/stretching work, all the better. That could be part of your negotiation with them.

With a single image, it would be a waste of time to start a blog, Web site or setup an gallery at one of the many online sites, as would approaching publishers, art reps, galleries and wholesalers. That said if you have more work, even if just originals, you should be working all those angles. If you persistently pursue finding creative ways to sell the image, you will prevail and it will all be great experience for the next time. Best wishes for success!

Thanks for your advice, or more appropriately - opinion.  To address the first thought, they were printed 4 years ago on the basis that my so-called "representative" would do just that and handle the distribution.  Unfortunately, I was left with the responsibility.  Being an artist, not an agent, it is my talent to create art, not sell. As for P.O.D., at that time, is was not an option. 

My preference would be to find another distributor or something to the liking that can handle things from here.  I am not in-experienced in gallery sales, quiet the opposite.  I deal 7 days a week with Thomas Kinkade.  Though his artwork isn't my taste, it obviously is to others. 

I am a self-taught artist, professional now for over 20 years.  I don't have the time to go "door-to-door" and find galleries to try to sell them.  Thank you for your advice, all the same.
