Extragoods World Puzzle 1000 Pieces

We wanted to swap out a kids 30" x 20" map of the world for a an accurate detailed 30" x 20" map of the world in the same frame, now that our kiddo has gotten hardcore into geography. But Amazon had no accurate prints in that size (just weird antique maps).So we ordered this puzzle: it's detailed, up-to-date, and it was advertised as 30" x 20". It would be work to put together, but otherwise perfect.It's a great puzzle. The longitude and latitude, colored countries, mountains/rivers/coastlines, and words all make it pretty easy for a 1000-piece puzzle.We ordered some puzzle glue and glued it together.We took the old map out of the frame, and started to put the new puzzle map in...This puzzle is about 27" x 18.75". I centered it on the frame's backing and pressed it into place, so it'll have to do. But I was _very_ disappointed that it didn't fill up the frame, since that was the only reason I ordered it in the first place.
