If you’ve been thinking of picking up one of my transit map posters, now might be a good time: Society6 is offering free shipping on prints worldwide until next Sunday, January 27.

Here’s some direct links to some of the posters I offer:

• US Highways as a Subway Map
• US Interstates as a Subway Map
• Amtrak Passenger Routes as a Subway Map
• Boston MBTA Rapid Transit (with key bus routes)
• Boston MBTA Rapid Transit (with Silver Line, without other bus routes)
• Rail Transit of Portland, Oregon
• Historical Passenger Rail of Portland, Oregon (comparing 1912, 1943 and 2015)
• International E-Road (European Highway) Network

As always, I highly recommend purchasing only the X-LARGE or LARGE versions of these prints: they’re designed as large format posters and type may become too small to be legible at sizes smaller than these.
