This t-shirt possibly qualifies as the first object I bought with dandelions on.
I bought it around 2005 ish from a lovely little shop here in Preston. The shop is no longer around, which is a shame. And the company who made the t-shirt 2Blame Clothing, also seems not to exist anymore. As i didn't have the Archive set up at that time, i didn't note the name of the shop or the date i bought it.
I wore it lots, but not for a long time now, but it's safe in the Dandelion Archive.
