I agree, Bill. My 2026 and its accompanying cars arrived at Christmas, 1951, and between Christmases, they were all kept in my parents' attic until I reclaimed them in the mid-Seventies. The cardboard (and the rolling stock) were all undamaged.
My parents' house was in Pennsylvania, where summer humidity can give the tropics a run for their money.
