What suitcase is good for putting travel decals on?

I really like to travel and when I was thinking about getting a vintage type of suitcase and sticker it with travel destination decals. I hope you know what I'm talking about. back in the day when people used to travel they'd get stickers or decals and put them all over the suitcase. I want to do that with one. My question is what kind of suitcases do they usually put the decals on. I can picture the suitcases I've seen in various antique malls and what not but I want to know possibly exactly what kind of suitcases they are so I can look them up by their specific names on ebay or other sites. Or possible some suggestions would be nice too. thanks
