I was down at one of our best local art/craft supply stores today and had another look at some reproduction world maps they sell. There's no copyright date on the original (the reprint is (c) 2003) but examining the borders, especially in Europe, gives it a date of 1919-1920s, no later.
It has to be post-WW1 (from Germany's borders and others), and lots of material from pre-1923 is now out of copyright in many countries, so that's probably the best range for the age of the original.
The reproduction is well done, very clear printing on nice textured paper. The original had some seam wear and minor discolouration that's been reproduced faithfully, but it's just extra character and doesn't obscure the details at all.
Made by
Cavallini of Italy as part of their 'Decorative Wrap' line of papers (link); the original map might have been by
Stanfords (link) as both company's names appear on this. The map is about 19"x28". Cavallini actually produce a whole range of 'Decorative Wrap' paper, almost all reproduced historical material and including a bunch of other historical maps - New York, London, Paris & Italy are all at our local art store.
Best part was the price: $4.50 Canadian! (about 2.50 Euro or UKP)
I'll try and get a quick photo of the map in the next few days; I can see using it as photo backdrops in the future too.
Edit to Add: This map has [wiki]Tannu Tuva[/wiki] on it, which means it cannot date later than 1926 or before 1921. From the linked Wikipedia article: "
Following the Russian Revolution of 1917, Communist troops took Tuva in January 1920. The chaos accompanying this era allowed the Tuvans to again proclaim their independence. On 14 August, 1921, the Bolsheviks (supported by Russia) established a Tuvan People's Republic, called Tannu Tuva until 1926."
Aside from Germany's post-WW1 borders (easy to spot), the existence of the USSR & Tannu Tuva, does anyone know any other geopolitical clues I could use to nail down a more exact date for this map than '21-26?
