Managed to keep 8 of these Bacardi cups from Lolla last year
The top pic was taken at the Vip lounge at Lollapalooza and was used in this article
about the food at Lollapalooza and this article
about the general VIP experience.
The second picture is just to show the text at the back and front as well as the bat logo at the bottom.
I've never used them since I got them but I think they would look cool in any bar and would look even cooler on a coffee table with a bottle of Bacardi 8 Year Old in the center;
