I stumbled upon this fine little gem, a little extravagent but quite cool. Product Description
Large brass cast or original Plaza Hotel room number on key chain with large brass lobster clasp. Number measures 2 1/4" tall. 601D (via hotel style)

i really like this but it is so over priced i coud not afford it, my cousin made one for me , he found the key chain part at our local 99 cent store , and plaza numbers from a fancy hardware store, all for under $10 I LOVE I T,I THANK THIS LULU what a great idea. i saw in a mathra stewart magazine where to buy these part cheaper than what i paid , go martha girl ........ but i now think this number idea is a little playeed (via ooh lala)
