My sister is sorting

Years ago . . .   like in the last century . . .   all of the things nobody wanted from my folks house was stored at one of those storage facilities you can rent.
I dunno what's in there, but she's doing a thorough job of checking what's what.
She sent this picture.

Somewhwere there are more pictures from that transcontinental train trip (both directions, two countries).

yeah, I can translate cursive
