Re Tuck Oblong Studies Albert Bowers

I recently purchased at auction a number of vintage postcards and amongst them are a series of ‘Albert Bowers Oblong Studies Of Tranquil scenery’ oversized postcards measuring 14" x 6" by Raphael Tuck series 542. I cannot find any information on them and wondered if anyone could shed some light ie date etc

We might have they in Ephemera, is this one?

@Billstock and Welcome to the forum.

Thanks I’ll check it out. I have done a little more research and they may be lithographs
