Hi there SLCforme,
I'm sorry, but I can not answer your questions except for I did find that photo in one of the threads here on this site. I liked the photo and wanted to add a few more buildings to it.
I am assuming that the Pioneer and Beehive towers were proposals at one time, but I have never heard of such a thing.
I think they are just made up (cut and paste) as I have done with the buildings that I added to the photo.
The buildings under construction are from Miami, some are from L.A. and N.Y.
The only building I know of that was an actual proposal was the Zions building (the tallest in my photo).
The photo of Salt Lake was not supposed to be of any style, I just like tall buildings and wanted to see what Salt Lake could look like if it had taller buildings.
Thanks for your input and reply.
It's nice to see that I am not the only one who likes tall buildings or would like to see our city change a little more in height.
Have a nice day.
Anthony
