[Hallicrafters] Hallicrafters Metal Sign

[radiofox]

Whilst going through a local antique mall in Ontario Canada, I found a 2' x 3' Hallicrafters metal sign - red background with lettering in yellow that says "hallicrafters long range radio - television".  Only info I could find on this piece is in Dachis book page 206 2nd edition - and shows a picture and suggests this is a 1950s piece. No values given in the back of the book, no production #s etc. . I bit the bullet and bought it - it was a nice clean piece, and it will grace my ham radio room wall (right beside the beer fridge).  Can anyone give me an idea of the provenance and value of this item - what year it came out, how many made, common or rare etc. Ive only seen these in pictures.
