A ‘glue abstract’ is created when a sign is removed from a wall and exposes the movement, often unintentionally artistic, of the person who was applying the glue.
This glue abstract was created when a metal ‘No Parking’ sign was removed from a wall and resulted in a study in black and white with a touch of ochre. Note that the black glue is thick enough to create light-weight shadows. 
This particular black glue abstract is really calligraphic, and overlaid with the translucent glue creates an interesting 3D quality to the artwork.
Another expressionistic piece.
Applying metal signs such as parking notices to concrete walls usually requires a really heavy-duty glue. And here we obviously have two very different glue artists.
Heavy-duty (and well-weathered) white glue forms a bas-relief on a concrete wall.
It seems a lighter weight ochre glue is appropriate for stucco surfaces. This one is quite lyrical, and I like that the pale yellow paint was ripped off creating a symphony in blue, yellow and ochre. 
Two different surfaces reacting differently to the removal of the sign.
I’m not quite sure how this polka-dotted glue abstract was created but I like it. 
This glue abstract on a dark blue door looks to me like a collection of beach pebbles.
Then there are the light-weight glues used for posters and temporary notices that create a wispier form of visual texture, like drifts of mist.

This one is from a series of graffiti and ripped posters on a construction barrier:Â Abstracts in Black and White.

Ha! I suspect no one else has glue abstracts! Outstanding!
Yes, but once I realized they were there I started seeing them everywhere, and I hope others will be similarly inspired!
Very interesting, Elisabeth! Inspirational. Covid brought something positive too.
Yes, I am quite inspired to start painting with a glue gun. It certainly is a completely different area to explore!
These are so unusual! Like Tina I am curious to know how long you have been ‘collecting’ these. I can’t think of a single occasion when I have noticed anything like this. (Or do you secretly remove the signs to get the photos?) 🤔

I would have to say that these are mostly COVID inspired, when I stuck to alleys and side streets and parking lots rather than the more popular routes where I could pass 10 people, two of them joggers, in the quarter block it took me to reach the nearest alley. They were almost all taken in 2020, 2021 and 2022, and within a 20 block radius of my home…
Wow, Elizabeth! I never saw this before. Fascinating!
I started walking in back alleys during COVID and saw a lot of things that I had never seen before.
Fascinating.
This is amazing Elizabeth! I have never seen (or perhaps have never noticed) what’s left behind when signs are removed. Candidly I don’t think we allow signs here on Kiawah so that may be why! But even in my frequent visits with family in NYC I’ve not seen anything like this – I absolutely loved all of them. Good for you for noticing – but I’m curious. Over what period of time did you find these and in how wide an area? They’re really terrific!!
All the photos except for two are labelled 20, 21 and 22 so they are almost all from my COVID walks along back alleys and less travelled routes. They are all from Vancouver except the ‘drifting mist’ one which is labelled 14Sp (2014 Spain). So definitely COVID inspired…
Very interesting and inspiring. I like it a lot.
I am also inspired by these pieces, and the unintended art creation when the ‘artist’ is handed a glue gun and thinks that their work will be hidden underneath a sign.
A realy special but indeed artistic way of creating art.
Have a lovely day and many greets.
