A Stamp for a Stone

Time to take the striped pebble to the big leagues! I rolled my prize stone past the sofa leg toward the tall bookshelf and hit the jackpot: a canceled vintage postage stamp with jagged edges and a bright red train, resting on a dropped bookmark! That paper looked rare, official, and totally collectible. I pushed my heavy tiger-striped pebble right onto the middle of the paper bookmark as an honest deposit, then scooped up the crisp stamp with both hands. It's featherlight and ready for circulation!#@
