Alan - Even in old age, my Dad used to listen to slippery sales pitches just out of amusement, causing them to think they were luring him in, then hit them with reality at a certain point, letting them know that, just because he was retired, he wasn't a sucker. He just liked to mess with their heads, and had heard it all before anyway. Guess I inherited that propensity. Of course, I was a professional buyer, so had to know the difference. But just out of curiosity, I've listen to, or listened in on, all kinds of sales pitches, including in both Lik and Kinkade galleries; and they were indeed slippery and misleading when it came to connotations of steadily increasing monetary value. It was the bait on the hook, if someone seemed unsure whether to make a purchase or not.
Now that took some concentration; because when I first walked into one of those galleries out of curiosity, along with my wife, I laughed, and said to her, "This is the worst stuff I've ever seen in my life; someone must be colorblind." I at least deserve some credit for being able to hold a straight face once it became my turn to hear the crocodile smiley BS sales pitch from the Babe in the tight skirt and high heels (my wife looked better anyway).
There are no laws in favor of good taste, or against bad taste. Galleries can do as they please in that respect. But there are laws against deliberately selling something in a deceptive manner that might cause financial harm to consumers. You can't claim a car is new just because it's been repainted and had the odometer fooled with. There are rules.
One can simply walk into an Ikea and get a big mass-produced and framed picturesque image every bit as good as any Lik print for two to three hundred dollars, without any predatory sales agent being involved. But like I already indicated earlier, in those Lik galleries, the sales people are evidently working on commission, and good at it, so will use every tool in their toolbox necessary to close a sale and squeeze the most out of it.
