I received a similar email as well. I googled for them, and found an interesting website called "Art Alarm:Suspect & Faux Art Venues." I can't vouch for this site, but it had this to say about World Art Media and their NYArts Magazine:
Says one press officer of my acquaintance: "The magazine is distributed to the pr-marketing people at these museums. They can't / don't make any decisions about whose work gets shown or enters the permanent collection. This is bull----."
Here's the link to the entire website:
It's a little hard to read, with that loud background image and yellow font color. But it did have some interesting info. Again, I don't know much about this website, who runs it, and how they evaluate these offers.
I'll say this much about World Art Media: their email to me smacks of a mass mailed form letter. Despite having claimed to look at my work, no specific references to either my name or work were given in the email. I think that this smacks of a money making scam for World Art Media. Besides, I don't even imagnie my type of artwork hanging in any of the galleries they claim to work with on their website. I think they just want my money.
Hope this helps.
