Looking for more Bling for your Kato 5th Avenue building? The square Tomytec Rooftop Billboard seems made for it. Fit is perfect and can be illuminated. Did anyone notice how the 5th Ave. building has #"101"and the Tomix large office building #4018 has sticker numbered "102".
Not sure how it would be structurally sound when the supports are hanging over the sides :-)
And that's not a number '101' - it's a circular symbol with '101' after it as an anti-copyright version of the name of the Japanese department store Marui, whose symbol is '0101' (just like on another of their buildings they used 'HWV' instead of 'HMV', and on another one they used 'Star Rabbits' instead of 'Starbucks' etc etc etc).
