does each canvas needs its own membership?

I bought two meurals canvas 1.  one for my up stairs and one for my downstairs.  do i have to buy a a membership for each canvas?

Adorama has the special where the membership is included for the first year.  Since i have two canavas, i was thinking of saving one membership card.  If each canvas needs it own membership, then i'll take one canvas to display my 50k images catalog i currently have while also displaying some of the free samples while I will use the other canvas as with the full membership.

Thanks!
