on a freakin' poster or pocket calendar I say don't create any posters or pocket calendars. "You" don't deserve to get paid just because you appear on a throwaway piece of poster board or paper. That's RIDICULOUS. If "you" are a good enough athlete to be paid like a pro, then GO PRO.
If you make the team, you will get paid what you are WORTH. I'm not going to support any team or organization with MY money when doing so means that every kid who shows up in a picture HAS to get paid to do it. I will just do without your picture, thank you.
