Question about special trading cards

I was wondering if anyone knew how some special cards were done. If anyone has seen rare cards with multiple images in them, for example: it has like maybe 4 action sequences packed into the card. say if you tilt it a bit, you’d see one action, a little bit more then you’d see another. etc… anyways I was wondering if anyone knew how it was done or what type of cards are these called… my dad said vernacular or something, I wasn’t sure.

i think i know what you’re talking about, but i have no idea how to explain it.

thanks rei… sorry bout that, I googled it off once my dad showed me the email and it said lenticular and I got the same site too. sorry for the trouble
