Guys, please just take note that besides the SD version of the
ComfortDelgro Celebrates SG50 ad (the one with the 3D ball pop-up),
there's a similar version of it on DDs as well.
Only differences are:
1) It's not a 3D pop-up this time, but it's a circular sticker
pasted on each of the sides & rear of the bus (ie, total 3
circular stickers),
2) the portions not covered by the circular stickers are the base
SBST livery of the DDs (not a wrap, but the original
liveries)
3) There's no mention of the 'ComfortDelgro' word on the circular
stickers (or at least what I've seen so far)
Just spotted 3726X (BR 88) with this version.
So just updating everyone here, ty. 
Add on to my earlier post, apparently SDs have this sticker ad
as well from others' spottings. 5050Z (BR SP) has
this version too.
