[78-L] RCA Collector's Item Record No. 1

[agp]

Just got my hands on a promotional 7 inch 78 produced by RCA for 
Colgate-Palmolive's Halo brand of shampoo. You guys probably have 
seen this one before. Its labeled "Collector's Item Record No. 1" and 
is The Jumpin' Jive by Lionel Hampton (mx.E3-CS-7921) b/w Hunka Dola 
by Benny Goodman (mx.E3-CS-7919). Its pressed on very thin flexible 
material, vinyl maybe, but its not a flexi-disc.

I assume that there is nothing special about the actual recordings, 
but I wonder if the was a Collector's Item Record No. 2 and 3 etc.
