Is during the Olympic the right time to sell my memorabilia??

From the viewpoint of a collector would they be more likely to purchase (and pay more for) my large original lithograph poster from '68 during the 40th anniversary of the games?? Or could the market for Olympic goods be saturated at that point? I would ume someone who would be willing to pay 1200-1500 for an original poster would be looking for goods often or would they be holding out for an event like the games....any Olympic collectors out there willing to share their opinions on this ??? thank you
