Vintage German Map Over 160cm Long - Relief Panorama Des Rheines Folding Colour

I can't see a date but was a loft find and kept with other German items and memorabilia from a European tour from around 1930. 

If you are here you know more than me, please do check out the pictures as they form part of the description and I have tried to capture everything. 

Paper cover has some light ragging around the edges and some discolouration of the paper from storage, but the folding map on the inside is in great shape. 

Dimensions when folded: 23cm x 11cm

Dimensions when unfolded: approx 160cm long!
