Just found these decals. I got them in 1987, the first year for The Vortex. I have more Vortex stuff somewhere. I also have an old frisbee for the original Bat where The Vortex is now. I have not seen that frisbee for years but I know it is here somewhere. 

Very cool; thanks for sharing! I think I remember seeing the same Vortex sticker, or at least a similar one, on eBay a few months ago.

When you find The Bat frisbee I'd love to see a picture of it - I don't think I've seen that souvenir before.

I was contacted by several people wanting to purchase these stickers. I have no idea what they are worth but decided to put them on eBay. I do have what I feel is a high opening bid on them but I am ok with keeping them if they are not worth that much. I have had them this long so I can have them that much longer if need be. I have other things from back then also I will list if I can find them.  https://www.ebay.com/itm/224243831083 

Very cool stickers! Good luck.

I scored a mint condition one of those bumper stickers and original “I Felt The Grip” button on eBay back in the spring, and more recently an original postcard. That’s my first time seeing the other Vortex decal though.
