Some buildings (The Palace is definitely one) are 100% Art Deco; I mean this in as much as a fool could tell straight away.
Some, though are (certainly for me) a little bit harder to determine. Such as the one below. I'm 70% sure this is Art Deco, but one of our 'experts' may correct me.
Wallasey Road, Liscard.
This is another one I see every day but know nothing about. I've never read anything about this building, but I feel it may have been built for the gas / electric board. I'm pretty sure one of them had a showroom on the ground floor in the 90s. Probably the wrong side of the water for most of you
