Honestly, I find it cool that Nene was involved in the promotion of the exhibition (which might explain why she signed twice on her Hakubi profile, like you can see a hint of it on the first pic)

That said, the photo booth (the free ones at least) was kinda nice, like if you position yourself nicely, you might get a nice photo... Like Nene's here.

I didn't take photo from the Rider 1 booth, but I did for the Blade one XD

Tl;dr, to me personally... it's kinda an insult whenever people scoff at homemade props people make for cosplay (esp for toku merchs and real life stuff) and saying that you can just BUY them. I dunno bout others, but to me... especially with regards to my props whenever I made/buy them for cosplay, I really did treat them with care. Like how I made my Blackbird... by the time I'm finished with the prop and using it, my attachment to that prop was similar to how attached Tsukasa was with his pink camera. There was a sense of 'history' in it; like even if the prop can't actually be used to take pics, when I sold that prop off to another cosplayer... I really found it hard to let go of it because I did pour all my Tsukasa feels into making that prop like how that 'camera' was a way for Tsukasa to capture the memories of all the people, worlds that he passed through. Yeah, I had that certain habit regarding my props. I tend to treat them as my characters would in series.
