Is it an issue of "Authentic Science Fiction Monthly."

[twerppoet]

Well, there's the Perry Rhodan series, but nothing is matching there either.

I suppose it's possible (barely) that I missed reading a science fiction series or two in my youth.

Wow! I actually had a set of these in my room, though not this story and in a plain brown cover. They were in the room when I moved in, and some of the first science fiction I ever read. The 'invention' clue is what finally turned my head in the right direction.

Tom Swift and His Deep Sea Hyrodome.

I won't be able to monitor a challenge for the next few hours so the challenge is open to any IPF member who wishes to post a challenge.

[Richard Brown]

Yes, it is a symbol or a sign. However it is not for a building as such. Here is another part of the symbol.
