An "I love Moline, Kansas" sign, $10.99. These are available for several towns in Elk County, as well as city limit signs except for Elk Falls. I don't believe I have ever seen anything for Elk Falls on Ebay.

More Ebay stuff,
Howard National Bank $5 note, 1902, being offered for $179.
An interesting view of what is apparently a Howard, Kansas, residential street, with an annotation of "6568 Residence Street," $10. I cannot place the corner but the streets are dirt. The sidewalks, though continue across the street. [Went back to take another look to see the year but the photo is gone, must have been a mistake]
