heed the seller's advice
Seller states that map may be difficult to read in smaller sizes. Listen to what the seller is saying.  I purchased the 24x25 size and I am so glad I didn't get the smaller version or it would have been hard to read.  Paper quality and color are very good.  Map came in a thick cardboard cylinder shipping tube and delivery was punctual.  I purchased from this seller because they did some minor color editing to fill in the blank areas on this reduced size copy of an extremely large original 1856 edition atlas map.  (Other versions of this map are available with the blank/missing spaces and seams 'as is' per the original--so it all depends are what you are looking for. I was happy to find the slightly edited copy.)  Be aware that if your intention is to frame an uncommon size such as 24x25, a frame can be difficult to find without going the route of custom framing.
