Are fans allowed to bring in fan-made posters to Ayu concerts?

I can't remember if I've actually seen any when watching her DVDs, but none come to mind, so I was wondering. For those who've actually been to her concerts, have you seen/brought any fan-made posters to hold up? Are those allowed?

When I watch the concerts, I could've sworn I've seen fans holding up fan-made posters. I don't think you get in trouble for bringing them.

Oooh it would be fun to make a poster and hold it up at an Ayu concert~! You might get on the DVD!

There's usually a size-limit to any fan-made items. It's more or less an unspoken rule, anything big would block the fans behind you. Posters are unusual, but homemade fans are common in Japan.
