I came across this article on a toy blog called “Astro Galaxy” about a series of bottle tops released in conjunction with Pepsi with various Star Wars characters on them. Not bad, but series 9 features spaceships from the original trilogy and one of them is our beloved Millennium Falcon.
The site says that this set was released in 2002. I’ve had a quick look on ebay, but they didn’t have one. This could be a rather nice one to hunt down.
Please let me know if you have any information on these.

These are from Japan (despite the all-English packaging). While Pepsi included many different bottle toppers with bottles of Pepsi at the time, there were also a number of these sets you had to mail away to get. I have the one with Jabba in it. They do occasionally appear on ebay.

Thanks. I’ll be keeping an eye open for them now. To be honest, i’m looking forward to the hunt.
