Harrison Trains sells some pretty interestingly named roadside signs and boxcars:
HALF FAST AUTO REPAIR " We can almost fix anything"
DOGGY DO CANINE LAXATIVE " Doggone it really works"
FARTZWELL BAKED BEANS " Making every meal a real gas"
AND some others that I won't put here on the forum, however, you can check them out at their website: HARRISON TRAINS and SCENES click on " Not for primetime products"
