Having promised myself that I would not buy any more Guildford postcards until I had a firm decision on what to do with the ones I already owned I broke my own promise and bought this one! I know, I have absolutely no will power!
I was totally intrigued and the postcard was exchanged for smallish note of British currency and it came home with me. It sat on my desk glaring at me every time I reach for a pen from the pen pot on my desk. Now, several months on I still have absolutely no idea what it is all about!
So, if you have any ideas please do leave a comment. In the meantime I have sent a digital copy of it to the Owston (Ouston) One-Name Study registrant.

I suspect that it was a curious marketing ploy of the time & that those who didn't get the clues might have visited the store to find the answer! I have just re-read your suggestion about wheat, whilst I had the wheat bit, I had not taken the thought a step further to (wheat) stock Lino.

It's definitely a ton (20 hundredweight).H. Ouston's ? Lino.http://www.1900s.org.uk/images-1938-table-receipt.htm may be a later manifestation of his business. Most fo the rest of his 'net presence relates to a 'famous' legal case (for some values of fame).

What was H. Ouston's business? That would give a clue.

I thought the first graphic is 20lbs & the second one wheat.

It is some kind of rebus. House – ton's (goodness knows) line hoe? I know this last bit doesn't make sense but given that he is H Ouston the first but does. Would help if we knew what the slightly dodgy looking middle symbol is.
