Renno I know through the BAV tradeshows. Already knew him from the times I was still collecting Dutch beer labels.
We never traded that much but he is always interested in the good (Dutch) stuff and has some nice to offer as well. Very good collector.
Special agreement meant that I received a bunch of, for me, good new Danish caps. Wietze got many unused U.S. soda caps, with and without cork-lined. Happy trading with an excellent collector. Welcome back.
Finally we "traded" some caps with him.
And one more time we got marvellous caps in return.
Always the best to meet him personally at the meetings.
He's the sunshine in the neon light shined trading rooms ...;-)
All the best for you.
