I'm in the Netherlands for one of the most prestigious Fine Art Atlantic fairs Tifa of Maastricht. There is one in New York, but this is the original flagship Tifa of Fair. The show is impressive using quality art pieces, spending 7,000 years, paintings, sculpture, tapestries, antique furniture, clocks, fine jewelry. The fear is known for its rigorous vetting process. Sometimes it results in last-minute changes in presentation, and that's exactly what happened to one of the exhibits. I'm Marius Vendamm. I'm the art historian who works for Columburg Antiqueurs from Osgrod, the Netherlands. It's near Eindhoven and our drive from Maastricht, so it feels like home here in Maastricht and we're happy to be back after two years. While working around the show, I couldn't help but notice this exquisite cabinet. Here's a story behind it. Well, we bought this cabinet during the pandemic from private collection and we knew it was something very special, but we didn't know what it was. So we talked to many experts over the world and they all said something different and nobody actually knew what it was. So, well, we tried to make a story about it and we made a report and then we put it here during build-up and then comes the vetting. The vetting is very strict and they work by and they read our cards and they say, well, well, could be, but we think it's something else. What is it? First of all, what did you think it was? We thought it was made in India because of the ivory, the tortoise, the way the flowers are made and the glass inside. And they said, well, that's a good guess and we should have agreed, but someone in our vetting committee knows what it is and it's not Indian, it's European, it was made in Hamburg and you couldn't know because the maker is a musical instrument maker, Joachim Tilke from Hamburg and he is the Strativarius under the guitar builders of the 18th century, of the early 18th century. So we had to rewrite our report one and a half year of research and we had to do that in one night. Last Thursday because the vetting committee comes here on Wednesday, they vet on Thursday and we hear around four o'clock what it is, but on 10 o'clock on Friday we opened. So I had one night to change the story and in that night I found out that the cabinet was described in 1711 by a traveler who went to the shop of Tilke to buy a guitar and he bought it the guitar for 50 gilders and he said, I thought it was very expensive. The literary term in his book is heavy money. And now you're selling it if it's not a secret? Well, we keep that for us, but it's much much more, he bought it. Well, and him was told that there was also a cabinet, then it was worth 800 taller, which is approximately 1200 gilders, then. And if 50 gilders was heavy money for him, then 1200 gilders was way beyond. Can you tell me when the gallery was established? What's the meaning? He was established by Misha van Kullenburg. He's the son of a clock dealer in the Netherlands and he started at a very young age, he had just 14 already with dealing in antiques. And he found it, well, van Kullenburg antiquiers in Oorskot around 2000 and we're attending Tefavs since 2015. Even though I've been attending art events for a few years now, the names of the exhibits are mailing you to me. It's definitely one of the most beautiful art fairs. It's worth a visit. I highly recommend it. This year marks the 10-year anniversary of the museum restoration fund. Each year Tefavs provides funding for a restoration of significant artworks. This edition's award goes to Dutch Museum in Rotterdam to restore painting poplars near Nullenburg by Van Gogh. The top layers of paint are in need of work since it was painted over another painting. Not everything is old. This is Pop Art, a Nade series BMW designed in collaboration with Jeff Klohn's. And the show was not without a drama. Did they have to have left on Tuesday? It was a jewelry heist. Here is dramatic video for the explainer. Again, a progress in the sledgehammer to smash open a display case and steal some jewelry. Evidently, the loot is a 29 million euro yellow diamond necklace, stolen from London Gallery, symbolic and cheese. Robbers remain at large. Tefavs issued a statement calling it an incident. Stay safe, everyone. From Maastricht, I'm Jane Greaves.
