Dear Sir / Madam;

I'm Jelle Buyse from Belgium and I'm a crewmember and balloon-items
collector.

Some months ago, I've made a web log (www.bloggen.be/ballonitems
<http://www.bloggen.be/ballonitems> ) where a put my new balloon-items on,
together with a link to the team…

I've already a extensive collection of Belgian balloon-items, but I want to
extend my collection of foreign balloon-items. Would you like to help me?

You can help me by giving and sending flight certificates, leaflets,
stickers, pins, cards, … I collect really EVERYTHING about ballooning!

Thanking you in advance,
