I recently purchased a '76-'77 Topps Basketball card, which are I believe the largest sports card ever made at 3 1/8” x 5 ¼”. I would love to put this in a one-touch case, but I don't think they make one for that size of card. If they do, I can't seem to find it. Curious if anyone knows if that case does exist and I just can't find it for some reason, or if not, how anyone else might put their '76-'77 card in a case. Thanks!
