While I don't advocate these overpriced collectibles unless you can find them on the third-party market (i.e., don't be the first person to buy it, be the second or third and let someone else take the retail hit), I wholeheartedly recommend the stamps themselves.
I don't buy many new issues, as I always have an overflow of discount postage. Those that I do purchase are of vintage designs that align with my appreciation of collectibles. For example, I love the Classics Forever sheets.
I wasn't planning to buy these train stamps, but when I was at the post office on Friday, the clerk had sheets of these out on the counter for people to look at and I was surprised how they look compared to the USPS renderings. What the stock images fail to convey is the embossed gold file of the frames. They really make the vintage look "pop". They definitely have that old west feel to them.
I took some cellphone pics to try and capture the reflective nature of the foil. Sorry for the glare; comes with the territory:
