Manhole cover

Oh, really! Interesting and kind of fun. If I was a collector of something, it would not weigh 50 pounds. ;-o

Indeed. You would need a (non-socialistic) palatial style residence to store them, and as for displaying them ... !
I have to say though that the design has been carefully worked out, the calligrapy and artwork is excellent and the overall effect is very pleasing.
But I don't think I want to start collecting them!

I have no palatial residence, non-socialistic or otherwise. I agree, most pleasing, and I've never seen another one like it in town. I should look down more often.

I've been inspired by that collection idea. I'm going to start with emeralds. Light, easier to ship and display, can be bought on eBay!

nice find, there should be more drain cover art
