Thanks for the photo...mine look like the top photo. And the ones I purchased for Wells Fargo look like the bottom. I just think the top tickets don't look legit based on all the markers they usually warn about counterfeit - 1) completely different ticket stock, 2) hologram is not in the right place, 3) where your tickets say "adult", mine say, "Imafan".
Yeah my understanding is that when you get the entire strip from allocations, the NCAA issued the bottom ones in advance for early sale. The top ones are the ones made available to the general public for venue distribution or distribution from the ncaa directly to the public. Considering IMAFAN is the NCAA ticket code for the tourney, I would venture it just means they bought from the NCAA not the venue.
