I was away for a work trip in London and Stockholm, and I took some pictures of their post boxes. The London postbox looks historical, i.e. like those postboxes from the colonial era. I think Singapore no longer has such red tubular postboxes, except for the one outside the Philatelic Museum. Posting personal letters from such historical looking postboxes should be fun. The postboxes from Stockholm look a lot more modern and fancy.

I didn't have much time for any philatelic related visits, partly because my work meeting timings were pretty tight. There is this Post Museum in Stockholm which looks interesting, and given time I would have pay a visit. Nonetheless I've sent some post cards back home, and once they reached I could post the pictures of them on the blog.
