Singapore NDP 51 Miniature Sheet FDC

On Aug.8, there was a Pop Up store at Toa Payoh Atrium.
Sold the Singapore NDP 51 related stamps and Rio Olympic Game Series.
Singpost also provided exclusive chops for the collector.

I like to collect miniature sheet. So ignored the other NDP 51 set.
The exclusive chops are the left corner one and the cancellation chop on the postage label.
You have to affix more stamp on the cover; the staff can chop the stamp with the special one day chop.
The pre-cancellation FDC is not allowed to have the "Birthday Chop."
That's why I affixed the usual postage label on it.

Attached more event photos.

You can see such a long queue. 

I think most of the people just join the queue when they saw so many people was there.

Looks like the event is fun and affordable, so participate immediately.
