Vintage T-Shirt Forum & Community Authentication Appraisals

Hey all, showing off a Smashing Pumpkins "Zero" long-sleeve that I found a couple of years ago at a consignment shop. It's definitely not licensed (considering it's a USA made blank from a company I've never seen otherwise, as well as the missing heart SP logo on the sleeve) but the quality, cut and condition of the material indicate age from the 1995 copyright date. Do you guys think this is a bootleg from an old tour?

Thanks for any responses!
