Up for auction on eBay is this fantastic salesman's sample case of miniature vintage telephones. It's an absolutely beautiful relic of telecom history. Each phone is 2" x 4" and the handsets lift! Current bid is $50. Link (Thanks, Michael-Anne Rauback!)

UPDATE: Thanks to BB reader Steve LaNasa who reminds me that phones of this vintage were usually rented from Ma Bell, not purchased, so the salesperson who carried this case was most likely selling contracts.
