I don't know anything about these stamps I had to ask my phone where they were from ? So I'll leave it to you who know there maybe some good ones and it has a channel tunnel souvenir booklet thing it was franked on the GB and french stamps on the 3rd of may 1994 I don't know if that is when it opened or if that makes it any better also I don't know if this is a mistake but on the french stamps it doesn't have a y it's just a line is that french or a mistake I'll show the GB first then the french and let you who know decide it will be well wrapped and sent signed for but I'll pay the extra postage thanks
