With this exhibit, I was lucky enough to go on the last week. Every other time I'd try to go the queue was massive and I didn't want to feel rushed. So an evening just gone was the perfect opportunity, with the museum closing at 5 we went at 4 for the last hour. This gave us a good 30 minutes to explore the exhibit, which we found was plenty.
Tickets did cost £5 for the exhibit, where the majority are free in the museum. The £5 is well worth the money to keep the museum running and to see such famous work. This exhibit was across the country in 12 cities with a bigger exhibit coming to London shortly. It celebrated 500 years since Da Vinci had completed some of his works of art.
When you enter the gallery there are booklets for children and also mini magnifying glasses so you can take a closer look. Some of the sketches, some of his first, with there being little details, where other the details out of this world for that era. Examples of the human body, the inner details for that time were spectacular. I was also shocked when the curator told us to actually get our phone out and attempt to take a photo of a thumbprint left on his work. As you can see above it didn't come out that well in the picture. One piece shows how he got symmetrical sides on pictures Da Vinci would pinprick the paper so it matched.
A room off to the side depicts similar drawings of such great detail, these are other artists. Huge detail into such animals as bird, frogs and even a bit of taxidermy. Although we only had half an hour this was plenty of time to take everything in and not feel rushed. If you missed it in Cardiff, get on down the queen's galleries in London and Edinburgh to see the glory or Da Vinci.
