Odd Original Handcolored 1747? Might be older Map Of North America Emanuel Bowen

Description

Original Handcolored Map Of North America By Emanuel Bowen..The colour might be a bit faded hard to tell how dark it should be. I did a bit of research on this map and was not able to find one exact to this one..All the others I found were dated 1747 in the top left corner but this one isn't .. Also all the others had a different page number in the top left corner.. Not positive when this map dates from... It does have two fold marks... The map measures 8" by 6 1/8" with the whole paper measuring 10' by 8 1/8".. It was taped onto a mate and will be mailing it still taped to the mat..I know this map is very old because it was in an old frame with a 1850 Lithograph behind it..Any questions please feel free..
