David, my only issue is the trite term of 'true fan'. It is 100% arbitrary and impossible to determine when discussed amongst poster collectors, sports fans, cigar aficionados, and so on.
Also, flipping keeps going to the fortune of some and misfortune of others because of the HYPE.
It is debatable what prints from Mondo even deserve the hype, but that is for a different day.
Regardless, you are the keeper of a fan site for all things Alamo posters and are inadvertently keeping the hype up, or adding to it in a sense with your site's mere existence...so there is that to consider also.
